Thursday, February 10, 2022, 12:24, David Wang, ITW, Standard Operation, , , ITW HV test without mdoule.
|
Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at
59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or
more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb |

|
Carla did the test. That is what she wrote in Feb 04th: "I am done with the HV testing at ITE - the
results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE
also has a band, from 54-56kV, where the current jumps around like crazy". |

UCX34# in pail 258(Vault lot 7C) has been repacked today. It is an investigation to find a possible leak source of radioactive Iodine in vault. The new
pail number is 268. It is back to vault 7c . I wrote down the information in log book. The job is smooth today. I retrieved UCx 34 old pail and liner
to TH. The liner from UCx#34 only has 3000 counts. I bagged it. It could be used later. However, the pail has 500K counts contamination on bottom |

Monday morning June 20th: TM2 with SiC # 42 was moved from ITW to NHC.
Monday afternoon: TM2 with no target was moved from NHC to SHC due to 10 pin connector guide pin loose issue. The guide pin has to be moved out
in SHC due to NHC manipulator configuration limit . |

|
With Ta#64 installed , TM4 HS line was helium pressure tested at TCS. base leak rate is 0.0XE-9 atm.cc/sec. HS line tested leak rate is 3x E-7 atm.cc/sec
on 5 minutes 50 psi helium testing. Leak check result wasgood at NHC by helium spray method. We decided to apply water to HS and all other water lines
still. The vacuum status is closely being watched. So far, TCS pumping down trend is still good. HS line supply water valve was switched on and off couple |
