Todo List for COLTRIMS setup: - AMOS Experiment at LBNL

COLTRIMS-Project Management:
Automatic Update
Updated: 6/18/2010
# Check Task Date Done
1 go after Rootsblower => Bruce has to be contacted again, and again,
and again. Rootsblower never worked. Totti found old rootspump –
exchanged the oil. Tests where made. Of no use for N2. For He it
might makes a difference – we couldn’t see any improvement for He
either on 7/20/2009. Pump stored in Storage2.
2 two convectrons have a problem: Check is needed (replacement).
Totti is on it. We have two working controllers and one broken
one. We need a salvage meter for the broken one (they don’t
make them anymore)
3 we need a drill and a stand for the workbench and a little vice for the
moveable workbench => Totti starts looking. Done.
4 electron detector needs new plates => Reinhard will supply a new
stack. Frankfurt people will bring it to the beamtime. We will also need
two ceramic rings and an MCP holder. Totti asked for that: Answer is
“Yes”. We get a complete new Hex detector. Totti will bring it.
5 decoupling box has grounding/noise problem: Needs test and debug.
Tim is building a new set + anode decoupling boxes with battery packs
(for MISTERS)
6 controller cart should be replaced by a 8020 design: Markus. The big
Helmholtz coils powersupply will go in a separate cart. Christian took
over. Parts are ordered and arrived (Dec. 2008). Christian puts it
together. (almost) done 1/8/09 (see task 178 below)
7 new coils + powersupply (=> Totti started to look around): Needs
planning, designing and construction. We will wait till Markus shows
up here. Got powersupply from 88: Mike Bell and Steve Cooper work
on safety (Totti). Coils: Markus is on it; hopes to finish with design by
Oct. 15 2008. Design finished in Nov 08 and 8020 parts are ordered
and arrived. Still at the safety guys (April 2009). Mike Fahmie (x4030)
is in charge for all safety issues and the final ok. Coils can be wound
starting first week of May 2009. Mike Bell will design holding plate and
connections until this. Coils are finished with winding in 77 (7/14/09).
Connections (plate) is still missing. Done (8/01/2009)

8 differential pumping stage: New tube (8 x 120mm ?) => Tim’s baby.
Sun took over. Ken is machining parts
9 repair of powersupplies, HP voltmeter, fast amplifier and CFD (Lothar
will repair the CFDs once he is here): Totti is on it
10 format data analysis computer, reinstall and get all the software
running again => Totti will get in contact with Jim and work on it: Done
11 a new 800 l turbo pump for COLTRIMS chamber is needed: Shimatsu
Totti: Seiko Seiki pump is repaired in time – we will use that while we
wait for the new pump
12 leak test for source chamber would be nice. No leak from outside;
micro leak is between last valve and chamber flange.
13 check all ion gauges. They are all functioning (as well as the
controller). Some filaments might be burned – so we might not have
two everywhere. Sun and Totti
14 marks for beamline 11 are needed => Totti will get in contact with
Hendrik, Tolek and Mary (survey group). Hendrik contacted me: They
will talk to the survey group but we have to check again. Scheduled for
January 30 th 2008. Done – marks are on the floor, but it is not clear
how far the beamline has to be rotated.
15 a new adapter flange chamber-to-differential-pumping-stage with
bellow would be nice: Needs ideas and discussion. Tim found better
design and is on it
16 make jet-dump tube moveable => Totti has an idea. Sun is
constructing. Ken is on it
17
cooling of jet is mysterious: What should we do ? Markus. Project
postponed (new cold trap with copper rod might solve the problem)
Cold trap is bad; only -115°C on copper wire, 10 cm behind trap. Most
likely connection between wire and trap itself. => new trap, may be
with complete rebuild of jet system
18 a Drytel for the differential pumping stage is needed: Discussion open.
Sun borrowed one from ALS
19 a forepump for the COLTRIMS chamber is needed : Discussion open.
We use a Scroll pump from ALS vacuum people (signed out by whom
?)

22 We need a little stronger powersupply for the rainbow coils: Done by
Totti
23 We need a ruler on the exit slits inside the chamber: We have to find
something made out of Aluminum. Sun did it
24 We need two RAMOS boxes in lab 102 => Totti: Steve is on it and
gets back to us. Outlets are installed.
25 SAFETY: There are still chemicals in the lab: What should we do ?
Totti contacts Jerry….
26 2 digital Frankfurt ratemeter desirable: Totti emailed to Reinhard and
Lothar. Answer is “NO – not now”
27 Exchange 3-fold SHV feedthrough with 4-fold SHV feedthrough: =>
Hunt for good one (1E-9Torr). Totti found one – hopefully it works.
Sun mounted it. Gives good vacuum.
28 SAFETY: Fasten the chamber to the ground. Totti: In progress…

30 Turn of the fume hood. Totti: Answer is “NO”. Hood is part of the AC
system of lab 102
31 Think about the use of a hex det and a 120mm for BL 10 experiment:
Hex Det = Yes. Detectors have to be set-up (put together and look for
wiring). We have to find out how the 80mm detector can be mounted
to the big spectrometer and how to lift the spectrometer or setup the
big spectrometer

33 We need an efficient beamdump for 30 to 55 eV photons (Woods
Horn): We will mount a 6in bellow at the exit of the chamber. Support
rods were constructed by Totti and are in the machine shop. We need
a good stand for the 6in pipe then (found something made out of
steel).
34 Spectrometer has to be simulated and designed: Need information
about KER and Electron energy first. Sun’s job and she is on it

installed on Markus and Christians computer.
65 Check and get Kwikflange (Hoses, clamps, rings…) and Swagelok
(valves, bending tool…): Felix and Totti
66 Connect printer to acquisition computer and get new cartridges: Felix
and Totti. Totti installed the printer; cartridges are new but print heads
are bad. Too expensive to replace. Buying a new printer (150$) is
cheaper (low priority)

6 New controller cart needed (8020): Markus. Christian took over; parts
are ordered and arrived (Dec. 2008). Some parts are still missing and
have to be ordered. Stuff arrived. Christian puts things together. Aluplates
for the top and bottom are designed and have to go into the
machine shop. They are now mounted. Frame is reinforced. Still some
brackets are missing. Feet got altered (4/12/09). Got plexi glass lips
on top. Frame is assembled. First modules went in (5/1/09). Feet are
ready to be attached (5/19/09). Modules have to go up to make a
complete unit fit at the bottom (6/2/09). Folder boxes needed for safety
and emergency shutdown list: Totti ordered something and mounted it
(6/9/09). Labels on Power cords are needed. Power has to be
redistributed evenly. Brackets are needed to attach chain for seismic
safety (chains and quick connectors have to be found and cut: Totti
found something for a start). Totti did it (6/4/09). Totti ordered double
8020 brackets for feet and installed them 9/18/09.
91 Aluminum plates (mesh-holders) for spectrometers need holes and
threads to take detector + new Aluminum arms are needed (to replace
the broken ones; done by Felix). Markus; scheduled for end of Nov.
Still have to go in the machine shop. Done
92
93
SAFETY: Complete check on all regulators for all gases and pressure
ranges: Markus + Christian; scheduled for Dec. => Regulators for
flammable gases (H2, CO, CmHn) tested and ok (3 x 60 psi, 2 x 600
psi); Rare gases, N2 (4 x 60 psi, 1 x 1200 psi). Have couple of broken
or unknown ones (will repair when needed). Look out for spare one
with high pressure (1000psi, rare gases). Good regulators are labeled
now.
New/big coils may need new 8020 arms (longer and perhaps
stronger): Totti (has to wait on Markus to finish designing and
construction of the coils first; 8020 profiles are available and need to
be cut then). Checked: Old arms do the job
94 Check LEMO, BNC, SHV cables, Ts, barrels and adapters: Markus +
Christian. SHV and Lemo cables, Ts and adapters checked and bad
ones rejected
95 Check the anode cylinders + new (universal) voltage divider or battery
boxes are needed (perhaps with potis). Think of 6 SHV connectors…:
Josh and Felix are on it. They put voltage divider in cylinders – works
well…
96 New voltage divider boxes are needed for the detectors (to have potis
would be nice): Felix is on it
97 2 more decoupling boxes for the spectrometer are needed: Felix is on
it

98 Moveable Scintillator going inside the spectrometer of any size has to
be constructed (attached to the chamber – not to the spectrometer):
Totti started looking around. Josh is building the support arm – did not
work; needs improvement: Totti took over and reconstructed some
parts and made a new rail system. Parts are ready, installed and work
“ok” (not perfect). Push-pull and 4xSHV feedthroughs got switched.
Arm for front phosphor is adjusted. Phosphor or Szintillator is still
missing and Vacuum test is needed (Markus)… See 138
99 Nozzle was clogged – we cleaned it but a jet test is necessary:
Markus. Nozzle is free – cooling remains a problem
100
SAFETY: Pumps on wheels: Get rid of the wooden boards (fire
hazards) and replace with Aluminum: Markus + Christian; projected for
January 2009.
101 Measure the convectron gauges: There has to be 20 Ohm between
pin 1 and 2 (if not it is likely to be broken). One can clean a convectron
with Alcohol or Acetone cautiously
=> moved down
102 We need a new MCP holder for 80mm plates that fit the 120mm Quad
Anode plus a ceramic ring with a big copper plate/ring on the front to
compensate fringe fields (recoil det): Markus, Sven and Ottmar
103 Electronic Rack: Rack blower in the middle has a damaged fan on the
right. Replace. Totti looked at it and cleaned a little with pressurized
air. Does not run great but is ok for now.

104 SAFETY: Rainbow coils: Replace orange plug. Totti did it 8/20/2008
105 SAFETY: We need more little electronic boxes with grounding (robust
style): Load Resistors, Voltage divider (for Grid or Copperplate)…
Especially 1:10 and 1:20 voltage divider are needed for monitoring
Voltages up to 1000 or 2000 V (Totti got input from EM shop: SHV-
Banana is not available – voltage dividers with output of max 100V are
okay in order to bring it to BNC). Totti ordered 20 boxes (for
COLTRIMS and MISTERS). Christian will build them and is on it.
Almost finished – tests would be desirable.
106 Decoupling boxes need mechanical support: Christian + Totti. 4
pieces are machined in the shop for COLTRIMS. If it works we will
order 4 more for MISTERS. Totti gave drawings to Rene. Christian will
order threaded rods and nuts.

107 Check the very short SHV-SHV cables for damage: They are poorly
made – very unreliable. Complain at EI shop (see 94): Markus +
Christian. 4 SHV bad cables found (still working, but plastic insulation
at connector damaged) => put in “useful broken cable”-box
1/30/2009
108 Manifold: Replace one valve with a lockable one. Totti did it. 8/15/2008
109 Phosphor: Front phosphor was weak and peeling off in vacuum (too
much glue ?). Totti spoke to David K. about flaking phosphor: We
made the layer too thick. He will help with air brushing phosphor on
glass plates – Totti and David did it. Small Phosphor or Scintillator for
spectrometer arm is still missing – Totti did it. See also 123 and 138
92
SAFETY: Check regulators for leaks and appropriate range (high
pressure). Markus + Christian
111 Rods for anode cylinders are still missing. Ken is on it. Totti will check.
Done and installed. Needed rewiring. Test would be good…
112 SAFETY: Check crane post for missing screws. Replace broken
brackets. Totti did it – not all the screws are in but it seems ok.
113 SAFETY: Check crane wheel at the tip. Totti did it and generated a
required crane log book
114 We need a NIM-NIM power cable – 10 feet long
115 Oil for the small 4 turbo pumps needs to be ordered from Pfeiffer:
Totti. Ordered 8/20/09. Arrived 9/3/09. Inserted 9/8/09.
116 Redesign MCP Holder plate for Hexdetector and Quad 80 (similar to
DLD120). Markus; will be finished by end of Oct. Still in machine shop.
(Jan 2009)
117 Ion Gauge in Source Chamber: Replace broken filament (David K.
might help us out). New filament available in ALS shop ($70) but we
might be able to use a filament from the old ion gauges. Totti did it,
see below.
118 SAFETY: Replace the 30 year old ion gauges with new ones. Cables
to connect to the old controllers have to be fabricated though (EM
shop). Totti is on it and bought 3 gauges. Gauges are installed and the
broken one is repaired with a filament of an old ion gauge. NOTE: We
are not operational because of the cables! EI people will order 4 “pigtails”
and modify our old cables. Work in progress. Done – test needed
(Markus who has to perform the vacuum test: 1/16/09 test done –
cable were wired the wrong way by EI shop). Now everything is ok.

Convectron gauge in Manifold has problem: Try to readjust or replace.
Markus + Christian; starts with 17 and 123. Oct. 15. => Manifold
convectron gauge shows right pressure.
120 Repair Phillips CFD 715: Center channel jumps in time (seen on
computer, it is not a cable delay problem). Give to Eric Henson. Totti
did it

121 Repair Ortec 441 Ratemeter. Give to Eric Henson. Totti did it 8/15/2008
122 Powersupply of Helmholtz coils: Display is broken; maybe more. Give
to EM shop. Totti did it. Back from repair. Should work.
123 Open the jet which got clogged during summer beamtime: Clean the
nozzle. Get new Swagelok filter. Remove mesh in front of nozzle !?
Totti prepared dismount of turbo pump. Markus + Christian. Markus
cleaned nozzle and put stuff back together. Jettest and vacuum test
(also of the phosphor feedthrough) is still needed. First test gave
factor too small rise in jetdump. Reopened and reduced the distance
to skimmer from 11 to 5 mm. Now jet is working fine (no new filter was
implemented though).
8/15/2008
1/21/2009
124 Check all 5 NIM bins (each slot) for voltages. Totti did it 8/16/2008
125 Pin at 120mm quad anode fell off. Solder…. Totti did it 8/16/2008
126 Re-center the Chamber on the frame. Adjust the little frame for the
differential pumping stage. Totti did it
127 SAFTEY: Earthquake brackets for Chambers in 102 and 104 are not
safe. Redesign needed. Totti did it – prototype will be made by Rene.
Prototype is now revised. Rene is making 12 stereotypes. Done and
installed
128 Harddrives in data acquisition and data analysis computer have to be
replaced. Perhaps order four 500 GB HDs (check if BIOS would be
happy with that). Think of the possible options. Matthias ordered HDs
and they arrived. However, there are not mounted yet. Markus will
replace some: see 148.
129 Monitor of data analysis computer has a problem. Might be still under
warranty. Totti is on it. Sent it out for repair. Came back and was also
broken. Send out again. Came back and works.
130 SAFETY: Multiple outlets near water lines (within 6 feet) need plastic
box: Totti did it

131 SAFETY: As found during summer beamtime lid needs support
threaded rods (+cylinders with delrin ends) to take the load in case we
open the chamber and work under the lid: Markus. Rods were
designed and machine in cooperation with machinist (Rene Delano)
and engineer. Parts in machine shop. Only 3 instead of 4 rods were
done. Test needed. Done: 3 rods are strong enough.
132 SAFETY: We have to find a way to get the LN2 out of the trap fast
and safe in case we have to open the chamber: Sun will ask Frank
Zucca. Markus will sketch a delrin lid with inlet for pressurized air and
an outlet for LN2 (+ pressure relief valve maybe). Totti took over:
Sketch was presented to Jim Floyd. He will think about it and get back
to us… Vacuum cleaner in combination with dewar might do the job.
Lid for dewar was constructed and machined with Rene (safety
aspects taken into account). Vacuum cleaner war ordered and arrived.
Test with water worked ok. Test with LN2 failed: The hose was too
small. Totti “organized” bigger hose (LN2 certificated) and insulated it
with foam. Test was positive. Rene makes new handle. Done – will
work.
133 Jetdump endplate and nut have to be milled down to gain some
clearance between the spectrometer and the Jetdump: Totti made a
drawing. It is in the machine shop. Done and installed. Jetdump tube
needs adjustment: see 137
134 SAFETY: Electronic rack has a broken wheel. Needs replacement
wheels (with brakes). Chamber wheels don’t look so well either (Totti
replaced them)… Markus; order goes out with 6 and 7. Markus and
Christian replaced the wheel.
135 Data acquisition computer has a driver problem with the DVD writer. It
can not burn DVDs. Totti tried to update the driver (but there are no
newer versions out there) and updated NERO. Still no success. Help
from somebody else is needed. Matthias did it: Cable was loose due
to transportation from and to the ALS.
136 SAFETY: ALS wooden roll stoppers need rubber pads. Sun ordered
parts. Totti cut rubber pads and improved 30 wooden brackets (we are
out of rubber pads and silicon glue again). Sun ordered more.
137 Jetdump tube in Jetdump-cylinder needs adjustment. Markus +
Christian + Sun

138 We need 5mm wide and 5cm long glass plates for the phosphor and
help from David Kilcoyne with airbrushing. Totti ordered new glass
cutter. Sun cut the class plates. Totti and Sun will approach David and
Hendrik. Phosphor is on plates (thanks to David). Plates were tested
at HH Laser in 458. We saw something and taking in account that this
was 10Hz it might work at the ALS. Totti remains skeptical…
139 Helmholtz Powersupplies need place to store them. Ask in building 2
and so on…: Markus. One powersupply (800 A / 20 V) got stored in
storage (warehouse). No place for the PowerTen powersupply has
been found yet (Feb. 2009). Put Powerten Powersupply in the back of
building 7 and labeled it 9/30/09.
140 SAFETY: New Helmholtz coils need save cable and water hose
connection. Plastic box is needed or similar. Markus will check back
on EI shop. => Plastic box is fine, still waiting for official safety
inspectors (April. 2009). M. Bell: “No water leak detection needed but
flow controller is desirable” (March. 2009). Temperature sensor would
be a good idea as well. Mike Bell took over. Done 7/31/09.
141 SAFETY: Administrative lockout procedure for gas manifold + labels +
swagelok cap are needed. Rene put cap on a chain, Totti made Alu
labels and wrote the admin. Procedure (which was forwarded to the
ALS safety staff by Dec. 18). Input from Donna Hamamoto and Will
Thur are expected for January 2009. No feedback to two more emails
– case closed for now.
142 Ne spectrometer has to be simulated (Allen) and constructed and
fitted to the chamber + the right offset flange has to be found and
mounted (Markus).
143 SAFETY: Portable box with Personal Protective Equipment for the
ALS beamtimes is needed (containing gloves, earplugs, earmuffs,
glasses, goggles…). Totti and Sun put something together. Wrong
earmuffs were delivered (RMA in process). Box still needs some
labels about the contents on the outside (Totti did it – waiting for
Earmuffs: Sun got them).
144 Spare blue HP NIM bin with broken 12V and a silver Tenelec NIM bin
with broken 6V was found at salvage area. Totti gave it to Eric Henson
(who is in the hospital for some weeks) for repair around Dec. 18 and
Jan. 22/08. Eric is out for a couple of months (3/31/09). Eric is back
but hasn’t started yet (9/10/09). Totti picked them up and brought
them to the ALS (3/21/10).

145 Gases have to be ordered: Ne, He, CO (gas cabinet). Markus. Gases
ordered (CO lecture bottle UHP, Neon bottle 80 research grade)
146 CF150 cross with turbo pump has to be mounted on recoil ion side.
Markus
147 8020 support of differential pumping stage is weak. 1530 Profiles
would be stronger. Totti ordered some stuff from 8020 (9/10/09).
Arrived 9/18/09. Needs to be mounted. Totti did it 9/25/09

idea and designs parts.
150 SAFETY: Quartz glass protection cover for CF40 glass flange on
Jetdump. Markus got one.

End of 2-Bunch-Run 3/2009
151 SAFETY: Thin green grounding cable on chamber frame (electron
side) needs to be replaced + there is another one with a loose
connection at the lug. We need more grounding cables as back-up
Christian + Totti replaced the bad and three short ones 3/26/09. We
now have some short spares (not really good ones). It’s still a good
idea to have about 5 good spares (AWG14, 1.25m long or so). Totti
took care of it.
152 SAFETY: Chamber needs motorcycle jack or something like that to
position it while it is elevated Totti thinks of transfer plates from
McMaster instead. Ordered. Is in 77 for welding (5/12/09)… Parts are
done (5/21/09). Test needed with new electronic rack for instance.
Have to wait on Christian to finish it first. Test done (5/22/09). Will
work but we need scissor jacks to stabilize chamber and take the
weight once we put the plates under the feet. Totti ordered two jacks
(arrived 5/26/09). Put a box together with transfer plates and scissor
jacks (under the workbench). Depending on the height of the chamber
wooden blocks might be needed too – we should look out for
something (building 7 and 79).
153 SAFETY: Last lockable valve on manifold was missing: Totti ordered
it; arrived 3/11; replaced it + changed admin lockout procedure.

154 SAFETY: Anchor bolts in 102 were pulled out of the floor. Totti filed in
work order 3/18/2009 and got in contact with Monroe Thomas. Hope
to get got more help form James Mankini… Mankini contacted Fred
Angliss (he will stop by 4/1/09). Steve Cooper stepped in and
contacted Tom Reese: Deeper drilling is necessary. That requires
floor scanning. Steve Cooper arranged for floor scanning (4/1/09). The
scanning report will be sent to James Mankini in the near future for
completion of the drill permit. In the meantime Fred Angliss took a look
at the floor and concluded the following: A) the wrong anchor bolts
were installed (they were not in agreement with his calculations). B)
The concrete is busted at two places, thus the tiles should come out in
order to take a closer look. C) He recommends replacing all 8 anchor
bolts with 3/8in HILTI KB-TZ, 2.5in embedded. The tiles have to be
removed wherever the concrete is busted in order to conclude
(together with Fred) if a deeper drilling would fix the problem or if the
concrete needs to be fixed first (Carpenters do that 4/2/09). Totti
moved the chamber for this purpose. Tom Reese will then send
somebody to take all 8 anchor bolts out. Done: Anchor bolts installed
by carpenter (Warren Elliot). Chamber back in place.
155 SAFETY: Main grounding cables have to remain with frame, pump
cart or electronic rack. Totti put labels on except controller cart (we
wait for the new cart here – done: Totti put label on 5/28/09)
156 Electronic/Detector tests: a) test new decoupling boxes and voltage
divider, b) lens potis, c) spectrometer voltage dividers, d) old
decoupling cylinders (150 Ohm, contacts, cable configuration…), e)
fast amplifier (need labels for polarity, amp. Factor) Christian.
Everything soldered and ready to be tested 7/10/09 (we need a
detector and spectrometer in vacuum). Done
157 Spectrometer voltmeter (on the right hand side of the rack) has bad
switch: fix it Totti. Took the front panel out and filed the slot for the
button a little bigger. Works better but not great.
158 MISTERS decoupling cylinders have to be modified as a back-up
Christian. Done 7/10/09. Test is still needed.
159 We have to buy more meshes (80%, 200 micron). We lost 7 sheets
Markus. Quote requested (4/14/08). Ordered (4/20/09). Arrived and
cut. Stuff was pretty crumpled on roll. Loss is estimated to 50%.
Markus complained at TWP Inc. but they don’t care…
160 We need a KF, CF and screw supply suitcase for the beamtime. Totti
found something 3/25/09. Nuts & Bolts supply is fine. We need more
supplies to fill the CF/KF suitcase. Totti bought some stuff, but KF25
o-rings are missing for instance (ALS shop is out of it)… got some
4/14/09. We now have the minimum equipment.

161 SHV-whip needs new label Totti did it. Decoupling boxes and
cylinders + voltage divider need labels and drawings etc. Markus did it
162 Data analysis computer is getting too slow: We should use Sun’s or
Matthias’ computer. Ali offered his PC and Monitor… We will use
Matthias computer as analysis computer. Needs reformatting since it
is fubar software wise. With IT service (8/24/09). Totti brought it back
from IT service and setup the accounts and put IT security software
on it (8/31/09). Needs ROOT, PAW, COBOLD, Background, Rate
Alarm, Backup Programs, Compiler, Origin, GS, Acrobat… Totti
started putting stuff on 9/17/09 (Cobold, Background, Rate Alarm,
Backup Programs, GS, PAW, ROOT, Compiler). Totti moved
computer to 2-102 and put it in gear 9/23/09. Markus put more
programs on it 3/10/10
163 Work on Jet: Cooling (new coldtrap), nozzle cleaning or new nozzle
design. Jet test with Roots pump for He (it might help) Markus. New
nozzle and holding parts designed and in machine shop with Rene
(4/9/09). First approach (using old coldtrap). New coldtrap is designed
and in machine shop with Rene (4/21/09). CF35 pipe was ordered
and arrived (4/29/09). Filter and gold gasket brought from Frankfurt
(6/03/09). Everything put together 7/13/09. Jettest on 7/14/09 without
and with Roots Forepump. Analysis of the results shows that rootspump
does not help. Performance with respect to the old design =
??? New coldtrap is still in shop and needs to be mounted (8/2/09).
Totti and Rene decided on the length and welding procedure of cold
trap. Material got ordered. Totti spoke to Bob Conroy how to attach
the copper braid. Rene drilled the holes in the rod and in the newly
designed clamp. Rene points out that knife edge on CF100 flange is
not wonderful – could be polished !? Copper bottom and CF100 top
flange is done. Next step: Cut the stainless tube by 6.5mm, weld cold
trap (Rene). Weld copper braid to clamp and rod (Bob) 10/29/09.
Copper rod + braid + clamp done and shaped down. Coldtrap
completely welded 11/20/09. Resistor needs to be attached and
jetflange on chamber rotated + new gas inlet + makeover of rainbow
coils (see 198).
164 Data acquisition computer needs recovery Markus brought it to IT
Service 3/20/2009; we might need to replace the harddrive. Totti
picked it up. New Seagate HD was installed. Updated XP, Symantec
and Spybot + defragmented C and D drive. Got rid of Spybot and
Symantec and put Sophos on acqu. and analysis computer.
165 New 120 spectrometer (copper plates + drift tube needed) Markus.
Spectrometer parts and det. mounting in machine shop. Alu pipe
ordered and arrived (4/29/09). Parts are in machine shop: copper
plate in 80, drift tube etc. with Rene… Core is assembled by Christian.
Drift follows… Resistors connected (06/25/09), Drift still missing. Done
7/10/09 (incl. mesh in front of Recoil Ion Det).

in place Markus. Parts designed and machine shop. Vacuum parts
found – some need testing (see 175). Need to order 8020 parts: goes
out with stuff for Christian for cart (4/24/09). Assembled (5/5/09).
Vacuum test needed. Vacuum is fine (7/14/09)
167 Rail for phosphor screen needs makeover Totti took it out of the
chamber and brought it to the machine shop. Rene is on it 3/30/09.
Totti fi(l)ne tuned the rail system and did a first adjustment. Should
work a little better now. Totti noticed that the black handle at the end
got loose a little bit and tighten it again using both little setscrews
(weak point)…
168 One more layer of phosphor on the glasses would be nice Totti +
David. More tests in the meantime shows that it works the way it is for
now
169 SAFETY: CSD guest procedure, Gasmanifold, JHA, AHD, OJT,
Emergency Shutdown List have to be in place Totti (is in contact with
Tracey Bigelow from HR; goes very slowly). Looks like EID can be
issued perhaps 2 to 3 weeks in advance. PGI form has to be filled out
before by every guest by all means 4/14/09. Watch out: There is a
new PGI form (unfortunately write protected). Because of that and a
missing internet interface at CSD we go via ALS again. We added a
new AHD like document for people to read before they work with the
COLTRIMS apparatus. The LBNL JHA system will face an overhaul
within 6 to 12 months. We have to wait for this outcome.
170 Apertures insets for slits in chamber needed Markus made one.
Daniel may makes a better version (no not really).
171 Program for automatic Backup (like FileSync) is needed Christian
installed it. It should be implemented in the red background box. Totti
put something together for coltrims/lbl and local account…
172 Spectrometer simulations for He experiment Markus is on it. Done:
Total spectrometer length 1.5 m
173 SAFETY: Noise exposure in labs 102 and 104. Totti is in contact with
Herb Toor and Rich Mc Clure from facilities for tests (Herb will show
up in 104 Mar. 23; for 102 we have to give him a holler once the
apparatus is running again). According to Herb: no probs (72 to 77db)
in 104 and 106. Herb stopped by July 14, 09 to check the noise level
in 102. It came out to 79db, which is no problem.
Herb measured the compressed air nozzles (9/24/09). The have
100dB – thus hearing protection is highly recommended. Totti put
warning signs in the three labs.

174 Get quote for modifying CF200 pipe by adding 2x CF35 flanges (77
machine shop). Markus: 1000 $. Different solution found (see 175).
175 Check recycled vacuum parts (bello and CF200 spool) for recoil ion
spectrometer arm with Frank Zucca. Markus. Equipment is at plating
shop for UHV cleaning (4/21/09). With Frank for UHV test (4/24/09). 2
out of 3 bellos are okay (bad one has label).
176 Get compass to check magnetic field orientation of Helmholtz coils.
Markus. Ordered at McMaster; arrived – is in toolbox
177 SAFETY: New Controller Cart needs seismic safety at least for 102.
Totti made drawings for the 8020 feet like at the chamber and gave
them to Ken Shiler (5/28/09) – done (6/9/09). We need a unistrut bar
and two long threaded rods for the ALS. Totti found unistrut bar and
rods + nuts and washers (5/28/09). Bar and Rod need to be cut. Totti
cut everything and assembled a bracket and labeled it (5/29/09).
Christian needs to attach 8020 brackets for attaching a chain (see 6):
Did it (6/4/09). Totti found chain and quick connectors as well as
shackles and bolted on some 8020 brackets: Might work – need
second opinion (6/3/09). New McMaster feet and threaded rods have
to be ordered – done and installed (6/18/09). Brackets are ready to be
drilled to the floor – need to know position first (have to wait on
Markus and Christian). Totti is in contact with Fred Angliss and James
Mankini. Fred Angliss approved 3/8" Hilti HIS inserts with RE-500
epoxy and 3/8" A193 grade B7 threaded rods installed with a hammer
drill and carbide bit in accordance with ICC ESR-2322 (see
http://www.icc-es.org/reports/pdf_files/ICC-ES/ESR-2322.pdf) and
special inspection during installation. Contact Johnny Johnson x5371
to schedule the inspection. Position for cart found and marked. New
floor scanning is needed (HIS inserts go 5 in deep) – done 9/10/09.
Monroe Thomas asked for Drill Permit. Monroe also has the epoxy
glue which is needed for the HIS inserts (9/17/09). Everything drilled
and glued 9/24/09. Totti and Rene drilled 0.5in holes in the brackets –
everything fits.
178 SAFETY: Totti got copper grounding plate from Steve Cooper for the
new controller cart (7/14/09). Christian will get screws and mount it:
Done. Diaphragm pumps need good grounding cable: Done. Strain
relief on one pump and plug on the other one have to be fixed: Still
has to go to Steve Cooper. Christian brought both pumps to Steve
(8/20/09). Totti got them and reinstalled them in the cart.

179 (8/2/09) Ion getter pump at BL 11 has to be moved out of the way.
Talk to Hendrik. Totti + Markus + Support
9/29/09 Remind Hendrik again end of November, begin December
(Shutdown in December). Totti writes email to Hendrik & Tolek
10/28/09. Did it: got positive reply on this.
12/07/09 Ion getter pump will not be moved away, but whole chamber
disconnected from beamline. Center pipe will also be dismounted.
180 (8/2/09) BL 11 needs glass valve for speeding up alignment process.
Talk to Hendrik. Totti + Markus + Support. Bruce Rude has thicker
glass window for VAT gate valve to comply with safety standard. Tony
Warwick has to be contacted and involved for the safety issues at the
ALS. Totti spoke to Tony and Jim Floyd: No radiation problem just
mechanical stability. Bruce Rude can give us the right window (he
also has the tool to mount it). Totti writes email to Hendrik & Tolek
10/28/09. Did it: got negative reply on this. What now ?
= moved down
181 (8/3/09) the new Helmholtz coils need two separate waterlines to be
reserved at BL 11. Talk to Hendrik. Totti + Markus + Support. Markus
let waterlines hanging at BL. Totti put remark on beamtime
preparation list (8/25/09):
http://amo-csd.lbl.gov/downloads/Checklist%20for%20Beamtime.pdf
182 (8/2/09) New Helmholtz coils need fixations: 8020 clamp on top and
8020 (with brackets) at chamber frame (left and right post). Totti +
Markus. 8020 brackets determined to be 5.5in long. Totti found 8020
material, cut it and mounted the pieces. We need to order brackets
and plastic end caps from 8020 plus more Velcro straps from
McMasters… (8/26/09). Totti orders from 8020. Markus orders from
McMaster (9/10/09). 8020 arrived 9/19/09. Totti put plastic caps +
brackets + velcro on 9/23/09. Test mount 8/25/09: works

183 (8/2/09) New Helmholtz coils need makeover: Connectors, tie raps, …
8020 arms need enforcement on the top part. Totti cut the water
hoses short. Totti ordered some 8020 stuff – 9/10/09. 8020 stuff
arrived and Totti put brackets on arms (not recommended to open)
9/18/09. Totti cut plastic hose and put the screws on the Coils. Totti
flipped the 8 Alu brackets to reverse up and down 9/21/09. Arms and
coils were aligned and test-mounted 9/23/09. Totti and Markus put
sleeve (McMaster 1459T17) around the power supply cables 9/24/09.
6 feet are missing. Markus orders more… Water hoses were cut short
9/30/09. SAFETY: Need new cover (Totti got rid of the sharp edges of
the interim cover). More sleeve arrived and Totti put it + low profile tie
wraps + yellow tape on the cables at the power supply and the coils.
Totti fixed the loose clamps on one coil 10/6/09. Markus designed
cover and ordered material; stuff is with Ken Shiler. Totti got parts and
gave it a shot – doesn’t fit; brought it back to Ken Shiler. 10/28/09
Covers are back. Totti found screws and assembled everything. Fits,
but we need to close the big holes on the bottom. (Old covers are kept
as spares in storage 2). Totti came up with sketch. With Ken Shiler
10/29/09. Cover is done and fits 11/10/09
184 (8/2/09) New controller cart should have rotatable wheels on backside
too for better maneuverability. Markus will order from McMaster
(30305T811); ordered 8/24/09. Wheels arrived and Totti mounted
them 8/26/09.
185 (8/2/09) 70l turbo pump (Alcatel) needs new place/mount at chamber
frame (8020). Totti came up with idea and brought sketch + turbo +
8020 (60x60) to Ken Shiler (8/26/09). Parts done 9/17/09. Totti got
them and installed everything on COLTRIMS frame. Shorter KF25
hose + curve and longer KF40 hose needed. Totti got everything and
installed it.
115 (8/2/09) Oil change for turbo pumps after beamtime (also the big
guy?): Totti. Ordered for the 4 small turbo pumps (8/20/09) – the big
guy looks ok, but second opinion is needed. Arrived 9/3/09. Installed
by Totti (9/8/09).
186 (8/2/09) Grounding plate on one side of the frame has to be moved to
the other corner. Longer grounding cable desirable. Put back the
grounding cable borrowed from MISTERS. Markus (8/26/09). Totti
removed the grounding plate from inappropriate position (pushed
upwards and flipped to the inside) – 8/32/09.
187 SAFETY: (8/2/09) more and longer plastic exhaust hoses are needed
(order for MISTERS as well). Markus. Ordered. Arrived 3/9/09. Totti
cut it and installed KF flanges.

192 (8/15/09) Storage and Backup solution needed for analysis and
backup PC’s (+ Server). Totti found “StarTech.com 3.5in Silver 4
Drive eSATA Multi Raid External Hard Drive Encl.” in eBuy (CDW-G).
Will order 2 of them after input from Frankfurt experts (Till + Jan).
Ordered two towers (incl. controller card) plus one additional controller
card (8/24/09)
Parts: StarTech.com 3.5in Silver 4 Drive eSATA Multi RAID External
Hard Drive Encl, Mfg. Part: SAT3540ER, CDW Part: 1584610,
UNSPSC: 43201802, Hard drive array - 4 bays ( SATA-300 ) - 0 x HD
- Serial ATA-300 (external), $226.00
1 Port PCI Express esata II controller card, StarTech.com ID:
PEXESATA1, $23
Stuff arrived and has been tested (9/4/09). Works fine for the most
part. The SiI Manager software on the computer with the non original
controller cart did not see the storage tower device. Totti called
startech and fixed it (see below).
If there is trouble with the non original controller card and “SiI
Manager 4726” software download the latest software from
http://www.startech.com/. Search for Product “SAT3540ER” on the
upper right hand of the webpage, download and unzip. Deinstall old
drivers and manager software. Reboot. Then go “start”, “settings”,
“control panel”, “add new hardware” and browse for the new “*.inf” file
of the download while installing the driver. Then install new manager.
There is a folder called “SAT3540ER” on the c:\ of TWeber-x09 with
the files. (controller card can stay installed in the computer while doing
all that). [Alternative suggested by Startech support: PEXESATA2 as
controller card instead of PEXESTA1; it runs the Sil3132.]

little bigger. Markus: New Cable/Clamps and Rods are ordered and
arrived. Cage posts need to be further apart + old and new rods need
to be cut + install new cable. 1/7/10 Totti made new stand-offs in
machine shop and mounted them. Exchanged Al rods at the vertical
side. New horizontal rods need to be measured, cut and mounted:
Done 1/8/10. Florian and Totti adjusted height (1/20/10). Florian and
Irina installed computer cable. Resistance checked. Should work.
Some cables still need to be fastened to the frame.

12/1/09 CO spectrometer simulation: Design is almost finished
(12/20/09). Drift tube needs to be cut + tapped holes for feet installed.
CF 150-250 Adapter is needed. 8020 support for CF250
spool needs
to be built. Check CF250 spool (is out of the dumpster). Markus brings
hexanode and mesh from Frankfurt. Totti borrowed 13 ¼ to 8 in flange
(Frank Zucca) and 13 ¼ to 2 ¾ flange (Eli Rothenburg); a second 13
¼ to 8 in flange would be better – got it from Bruce Rude (1/14/10).
Florian and Markus build spectrometer and fitted it into chamber
(3/10/10)
163 12/1/09 Jet cooling still needs to be put together and tested. Gas inlet
is missing. Glands have to be ordered and welded to new stainless
steel tube – Glands arrived 1/710. Florian brought it to 77 (1/22/10).
Parts came back and were installed. Leak found on nozzle to copper
block connection (insert was tightened). Works but no big
improvement for cold jet (-125C at Nozzle, -153C at Coldtrap Copper
rod, ideal would be -196C).
200 1/19/10 Data acquisition computer crashed with blue screen
and was
unstable after reboot. Totti imaged operating system to a new
harddrive with IT service and exchanged SATA cable.
201 1/26/10 Connectors for 12pin feedthrough (anode) and perhaps for
SHV feedthroughs are needed. Florian found pins at http://www.multicontact-usa.com
– part-number 41.6000, type B1-TH (1/26/10).
Orderd and arrived. Florian made new cables

202 SAFETY: (2/17/10) Jet cold trap sends condensate water on rainbow
coils, Helmholtz coils, floor and perhaps a pump if located
underneath. Foam or water collector is needed. Markus ordered three
sponges and some absorbent material (3/5/10) . Test needed.
Absorbent material didn’t help much. Totti installed some sponges.
Test needed (4/2/10)

New spectrometer plates mate from phosphor bronze – ordered at
McMaster. They were supposed to be flat (not from a coil), but have
still been curved too much. Even with putting force on the mounted
spectrometer stack, the
distance between two plates can exceed 30
%. -> Don’t take phosphor bronze from McMaster for
spectrometer plates!!! Markus

204 (3/9/10) Allen and Markus gave feedback about drifting and jumping
spectrometer voltage: Totti ordered two Standford PS325 and a
rackmount (3/9/10)

115 Oil for big turbo pump needed: Markus ordered from Pfeiffer (2/15/10). 6/10/2010
Arrived 3/10/10. Needs to be filled in… Done 6/10/10
