Wednesday, February 06, 2013, 14:34, Bevan Moss, Conditioning Station, Development, TM4, CS Test Target #1, 40kV All Common w/o Water Test 
|
Today the module was biased to 40kV in the conditioning station. The current draw was 0uA. Sparking started at 27 kV. I have attached the recording
from the strip tool of the vacuum while we were testing. After consulting Pierre if we should take the module to a higher voltage it was decided not to.
The purpose of this test we to check the interaction between the module, cover, new cooling line, EE and EINZEL cables. This test was considered a success |

Monday, March 17, 2014, 15:39, Keith C Ng, ITE, Repair, , , 2a3 window - prep and clean
|
Cleaned top of the ITE vacuum flange and top of window clamp. Attempted to clean the bellows/beam pipe through the wall, mostly dust and small particles.
When cleaning bottom of the wall penetration we picked up a stone/fragment and the vacuum stopped. Appears to be a rock of some kind. 800cpm.

|
Continued with vacuuming inside wall penetration to remove debris. Changed filter bag in nilfisk vacuum, left old filter in place however vacuum continues
to stall after >5min use. Vacuum gets quite warm before self shutting off. Debris seems to be falling back down on to joint if vacuum is turned off.
Took some screenshots of video showing removed debris and rust(?) on beam pipe. Video located on remote handling group folder. |

Wednesday, April 16, 2014, 17:08, Keith C Ng, ITE, Repair, , , 2a3 window - He leak check
|
Helium leak checked 2a3 window after installing using remote line:
- There was a leak found between the target and entrance module at the target pit, rate of 9E-6 atm-cc/sec.
- One test performed with the remote helium line to the window. There was a response but the leak detector was located above the window access |

|
Yesterday we installed the 2a2 window, the drive screw was torqued until 70
ft-lbs and we stopped, the yoke is not fully closed to its hard stop with roughly 7/8" to 3/4" still to go. Similar to identical conditions to
2a3 beamline window install, see https://elog.triumf.ca/TIS/RH-ISAC/647 for that install. Otherwise |

|
Leak detector is connected to ITW TP4. LD Base leak rate 0.0XE-09 atm.cc/sec. Helium line is connected to existing window leak check 1/8 " copper
tube. Applied 18psi helium for 1 minute. No response on LD. The window seal is good on ITW vacuum vessel. |

Friday, May 04, 2018, 11:21, David Wang, ITW, Repair, , , 2A2 winodw leak check in TH
|
Anders and I leak checked new 2A2 window seal on ITW side. Leak detector was connected to ITW TP4. Base leak rate 0.0Xe-9 atm.cc/sec.
base pressure 0.0xe-4 torr. Sprayed 15-20 psi directly underneath 2A2 window by using exist 2a2 window leak check copper tube. The leak detector
got response in 5 seconds when helium was applied. the leak rate was 5xe-6 atm.cc/sec. Once the helium source was closed, the leak rate dropped quickly |
