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