Wednesday, October 03, 2018, 14:16, David Wang, South Hot-Cell, Standard Operation, TM4, Ta #57, Leak check TM4 Lp Ta# 57 at SHC.
|
Tried to leak check TM4 Ta57# at TCS. LD failed to pump down properly at fine range. It always tripped at 4 torr. I cheeked all vacuum lines seals and adapters on top of module to LD. Everything is good. Chad said the VCRs at SHC can not be tightened any more. Discussed with Anders, we decide to move module TCS and helium pressure test there. The same difficult happened last time on TM4 UCx24# at SHC when leak check. But,it is solved by pressurize the line at SHC last time.
The HS line was pressurized with 70 psi helium on Oct 04th at TCS.. LD 0,00X E-9atm.cc/sec no change in 2 minutes. No leak. |

Tuesday, October 09, 2018, 12:32, David Wang, Conditioning Station, Repair, TM4, , TM4 steers 4 pin feedthrough CF flange
|
TM4 Steers 4 pin feedthrough CF flange is replaced due an inside feed through insulator broken. CF 25 cooper seal is replaced with a new one as well. Travis did anelectrical check. after replacement. Everything looks fine.
Note only a megger check was performed on the affected steering lines. Open load was measured on all lines. (Travis Cave) |
