<pre>Visually inspected SB0W11, which has problems biasing. 
Basically, found nothing visually.  See PC e-log 
for details.  COT baggy is supposed to go on at 5 
so we decided not to attempt anything drastic.</pre>

Did some East FTM work.  Fixed <a href=

'/cgi/elog/det-system-elog.pl?nb=e360-SVX-C-BRL-E-End-P-6&action=view&page=1&frame=2&anchor=06:47:48'> 
SB3W6</a>  
and possibly understand better the  <a href= 
'/cgi/elog/det-system-elog.pl?nb=e440-SVX-E-BRL-W-End-P-4&action=view&page=1&frame=2&anchor=08:26:49'> 
SB4W4</a> problem.  Current FTM status (to the best of my knowledge) is <a href = '/daq/core/cdfvme/FtmToFix.html'>here</a>. 
In general, no more FTM investigations on the East.  Waiting for 
West Cooling work to cease before continuing with the West.

<pre>The wierd thing is that I was attempting to put this into
the PC e-log, but for some reason it put it here.  On my second attempt I forgot to click "html".  On my third attempt I succeeded.  (See PC E-log for SB4W4).</pre>

<pre> 
Inspected West Side prior to baggie.  Found the following: 
 
&gt;&gt;&gt;All junction cards are still plugged and OK.&lt;&lt;&lt; 
 
A few HV connectors had come loose: 
   S7IN was not banded, HV connector off by ~2mm.  Fixed. 
   S6IN was not banded, HV connector off by ~1mm.  Fixed. 
   S11OUT not banded, HV connector completely off.  Fixed  
      and banded. 
 
A few RTV problems were noted as well, either on the clock- 
wise (CW, +phi) or counter clock-wise (CCW, -phi) side of  
the JC.  These cards were poorly RTV'd (and not fixed): 
   OUT3  -phi 
   S8IN  both sides 
   S7IN  +phi 
   S4OUT +phi 
   S1OUT -phi 
   IN0   -phi 
   S9OUT +phi 
   S5OUT -phi side has no rail, and backside has no RTV 
 
Rasnik-boy (aka Dave) checked line-of-sight, and bagging 
commenced at ~20:45.

<pre>Inchworm Status (Work done between May 30 and June 1) 
--------------- 
 
We have mounted protective covers on 4 of 5 inchworm motors (the other one was "too well protected" by cables to reach). 
 
The total weight on the inchworms has increased by about 8.5kg over the course of the shutdown. This is almost exactly what we should have expected (note the tense) from the addition of about 100 junction cards. It indicates that the cable strain-relief is taking most of the weight of the cables -- good news. 
 
There have been several ~100 micron displacements obeserved on the inchworm position monitoring during the shutdown -- unrelated to our deliberate motion of the motors; which introduced a 20 micron shift. 
 
Finally, at about 14:00 on May 31 we observed a sudden, 4kg, increase in load on the South West inchworm motor. Matt, Michael and I investigated this at 19:00 Thursday evening -- just before the baggie was due to go up. We found that we could relieve a few 100g of the load on this motor by relieving stress introduced from a number (5 or 6?) of the cooling pipes. Apparently the ISL cooling was being re-configured/re-connected on the west side at 14:00 on Thursday. We were able to reduce the excess load (the 4kg that appeared Thursday afternoon) by about 0.75 kg by re-arranging cooling pipes. We didn't find any one that seemed to be responsible for a significant fraction of the increase. We couldn't "improve" the strain-relief on several others (each of which might have alleviated a few 100 grams). 
 
We should think about why this addtional load appeared at this late stage -- the cooling has been connected before without causing such an increase. Hopefully there isn't a pipe that 
we couldn't find that is still under 3kg of tension.</pre>

Rich Stanek set the ISL and SVX chiller setpoints to 10 deg. C from 16 degrees. One sensor reads low: TE-CHLR_1 but the system looks okay otherwise.

    <h1>FTM Investigations on Friday, June 01</h1> 
Lester and I worked on the NW crate, making light output measurements and 
debugging and fixing problems.  The "DAQ Problem" 
<a href='/daq/core/cdfvme/FtmToFix.html'>web page</a> has been updated.  The short story is we investigated 
90% of the problems on the SVX NW crate and fixed 50% of them.
