Entry  Friday, October 28, 2011, 14:42, Bevan Moss, South Hot-Cell, Maintenance, TM4, , Leak check on service cap feed through IMG_1906.JPGIMG_1905.JPGIMG_1908.JPG
 After Chad and Davids leak check results from the containment box it was decided to perform a leak check on the feed through stem in the service
cap. This is a known point of failure on TM1 and the same design flaw is likely in TM4. Once the service cap was open a visual inspection was performed
and some oxidization of the copper line on the tube heater (+) circuit was observed (see attached pictures). The leak check was performed with the cart
Entry  Friday, October 28, 2011, 14:29, Bevan Moss, Conditioning Station, Standard Operation, TM4, , Leak Check on October 27/10/2011 
A leak check was performed on the module on October 27/10/2011 by David Wang and was reported to Bevan Moss but it never made it into the Elog system.
This entry is to summarize the results of that testing. All circuits were pressurized to 80 psi with helium and every line except the tube heater (+) showed
no or small responses as experienced before. The tube heater line had a slightly larger response under the conditions summarized below:

HP febiad target SiC#26 was installed onto Tm4 on Monday morning.
"JP's" connector required lossing of the two mounting fasteners. Connector was pushed tight to its mating half on the source tray and
both fasteners retightened, and the mating checked; it was good.

Entry  Tuesday, October 25, 2011, 16:57, Bevan Moss, Conditioning Station, Standard Operation, TM4, , Turbo Pump 1 issues 
Roughing on TM1 started at ~15:00 today by ~16:30 the module had reached a pressure of ~200 mTorr and the turbo pumps were turned on. TP1 failed to achieve
normal operation and we running at approximately 4KRPM and 50W with 6.1 A of current draw. TP2 was able to achieve normal operation. The controller for
TP1 was then powered off and back on but that failed to resolve the issue. The controllers for TP1 & 2 were then switched at which point TP1 again

Entry  Tuesday, October 25, 2011, 08:47, Travis Cave, South Hot-Cell, Standard Operation, TM4, SiC#26 High Powered, Electrical check 
TM#4 with SiC#26 HP has been checked electrically it has passed. It was noted that the Megger check of the Oven to Chassis (earth ground) and Oven to
60kV Common is low but will not hinder running, according to Don Jackson.  Also yesterday the transition piece that sits on the 55 pin connector was
damaged from excessive handling, it was removed and repaired and it now back in place.

Entry  Thursday, September 01, 2011, 09:11, Don Jackson, ITW, Standard Operation, TM1, UCx#2, Argon Venting West Station 
West target station is setup to use argon for tank venting.  There is 1200 PSI remaining on argon bottle in electrical room.  That is sufficent
for venting west target station to atmosphere twice.  ISAC Operations has been previousily contacted and their procedures for venting remain the same
except that they can not rely on ITW:CG4S to determine when at atmospheric pressure.  I have asked them to contact me if an unscheduled vent is required.
