Over the period of July 20-21st TM1 had several repairs completed and tested. The easiest of the repairs was the installation
of a gasket and a blank off. The next repair was to replace the 2 oring on the side panels that were removed for inspection and repair. The instrument
panel oring was replaced again and the previous one measured. Both were found to have the correct diameter of 0.131 inches for the seal groove. When attempting |

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 |

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: |

|
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 |

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. |

Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3
of the 16 looked at were too hot to ship and assay. See attached pdf for complete details. |

Well the first of this year's lucky winners to win a fabulous one way trip to Chalk River are as follows. UC#1, UC#2, Ta#25, Ta#26, and Ta#37. First
these lucky winners will get to stay several days and night in the lovely all inclusive mini vault before being loaded in to their very own private F-308
flasks to be whisked away off to fabulous Chalk River. |

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to
storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini
storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for |

Hi Remote Handling,
The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should
be reading about -20inHg and the bellows should be contracted (i.e. compressed). |

All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January
10th and the flasks were moved to rad waste on January 11th. Contamination was found on the bottoms of some of the pails and was removed, some of
the contamination was difficult but not impossible to remove from the pail bottoms. |
