 Thursday, January 11, 2024, 13:54, David Wang, Conditioning Station, Development, TM3, , TM3 servic cap air to vacumm seals leak check.
|
After Tm3 service tray and service cap installation, TM3 service cap air to vacuum seals leak check has been done at TCS. TCS:IG1 and IG1S are at low
E-7 torr range. leak detector base 0.0XE-9 atm.cc/sec, base pressure0.0X E-4 torr. I sprayed helium to all new air to vacuum seals
on service cap. No leak on seals. The leak check has been repeated 2 times with same result. |
