Wednesday, June 22, 2022, 09:03, David Wang, ITE, Standard Operation, TM4, UCX37# P2N, Remotely removed TM2 from ITE to NHC
|
| TM2 with UCx#37 P2N target was removed from ITE to NHC yesterday morning. The move is good. |
|
Wednesday, June 22, 2022, 09:14, David Wang, South Hot-Cell, Standard Operation, TM2, SiC#42 and SiC#43. , Three of TM2 moves related to SiC#42 to SiC #43 target switching job.
|
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 . |

Thursday, June 23, 2022, 13:04, David Wang, Conditioning Station, Standard Operation, TM4, Ta#64, helium pressure test on TM4 HS line.
|
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 |

Thursday, August 11, 2022, 09:10, David Wang, Conditioning Station, Standard Operation, TM4, SiC #44, HS line helium pressure test. Gas line fitting on module top and gas line leak check.
|
HS line helium pressure test is done at TCS. No leak. I also leak checked gasline adapter and fittings on TM4 top. No leak. 1/4 copper gas line
between module and ITE was leak checked yesterday. It is good. |

|
| TM2 with UCX#39 HS line helium pressure test is done at TCS. 70 psi helium 3minutes. No leak @0.0XE-9 atm.cc/sec. |
|
Wednesday, October 05, 2022, 09:31, David Wang, Conditioning Station, Standard Operation, TM4, C#4, HS line helium pressure test. TM4 with C#4 at TCS.
|
| TM4 HS line helium pressure test is done. 70psi helium pressure@ 3XE-8 atm.cc/sec . No leak. |

Monday, October 17, 2022, 08:07, David Wang, ITE/ITW, Repair, TM4, , A small leak on target station secondaryvacuum back up line by ITH MP1S.
|
A small leak in target station secondary vacuum back
up line is observed. It affects ITH CG2S,CG1S and CG4SA. Current draw on TP1s and TP4S is getting higher(above 1A) because of it. An internal leak in
ITH MP1S is suspected by first round investigation. Close watching on system and further investigation are needed.

|
| Helium 70 psi. tested 5minutes at base leak rate 0.9 xE09 atm.cc/sec on HS line. No leak. |
Friday, January 06, 2023, 10:38, David Wang, ITW, Standard Operation, TM2, , ITW/TM2 vacuum vessels leak check and TM2 internal cooling lines helium pressure test. 
|
ITW
and TM2 primary and secondary vacuum vessel leak check is done. Leak detector is connected to ITW TP1. Base leak rate on leak detector is 0.0 x E-9
atm.cc/sec. See attachment for the result. No big issue. Two old leaks we found last year at location D and E disappeared in this check. |

|
ITE primary and secondary vacuum vessel air to vacuum seals leak check was done this week. One leak has been found on IG1S feed through to entrance module
surface seal. It explains what we saw on ITE IG1S readings change(from low E-7 torr to 1Xe-6 torr) on December 22, 2022. This leak seal will be replaced
soon. |
