|
TM1 full leak check in conditioning station has been fulfilled this morning.Both air to vacuum leak check and waterlines helium 80psi pressure test are
fine.The result:
Air to vacuum helium spray:base leak rate on leak detector 1.6x E-9 atm .cc/sec.base pressure0.0xE-4 torr. sprayed helium around all flanges, turbo |

|
TM1 was high voltage tested without a target on November 16, 2011 with Don Jackson, Pierre Bricault, and Bevan Moss. The module was able to hold
up to 25 kV but between that and 32 kV there was lots of discharge which could be measured in the vacuum. See the attached plot for the voltage current
and sparks. |

TaC#1 was moved from the south hot cell to the storage vault. It was placed in pail#92 and put in vault slot 7B. It was 239mSv/hr upon removal from the
south hot cell. |

|
Inspection of TaC#1 showed that the oven was indeed broken on the A+ (left oven leg) side of the central block.
See the following for pictures.

|
November 15, 2011 removed TaC#1 from TM1 and inspected TM1 for any obivous signs of trouble (Problems with EE at end of run).
Upon starting removal of the high current conductor fastener on A+ (Left oven leg) it became clear right away that the oven of the target was broken
as the leg moved as soon as the fasten was loosened. |

|
For the week of November 7th 2011, four of a possible ten targets that are in storage were assayed. Targets are as follows:
Target General average field @ 1 metre from edge of pail
SiC#24 1.99 mSv/hr |

|
The silicon carbide targets voltage was raised to 42 kV today before continuous current draw was observed. It took roughly 10 minutes to raise
the module to this voltage with only the occasional spark. The ION gauge reading was 2.0 x 10^-6 T, The service cap IMG 3.6 x 10^-6 T, and the secondary
vacuum was 4.5 x 10^-6 T. Setup check and conditioning was performed by Pierre. |

|
I did a leak check again on TM4 today. This time, the leak detector pump to the bottom on both base pressure(0.0xE-4 torr) and base leak rate(0.0xE-9
atm.cc/sec). All high vacuum gauges on TM4 and conditioning station at -6torr range.IG1 is 3.3-6torr,PNG5(top of service cap)is 6.5-6 torr, and the PNG4(bottom
of the vessel )is 8.7-6torr. For air to vacuum leak checking, I checked the panel we moved last week on service cap by spraying helium around the panel. |

|
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 |

|
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. |
