Pail 237 only has 200u sv/hr field at 0.5 meter. On contact measurement: 0.9 to 1.6 m sv/hr.and less than 80 count contamination outside the pail.
It is moved to mini storage. We will transfer this pail to cyclotron vault and store it there later. |

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. |
