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