|
Frank and Anders disconnected the water and electrical connections this afternoon after the target was conditioned over the weekend. The heater ramping
program ran with the wrong gauge selected, causing the vacuum to go higher than planned. The module will be moved to ITW tomorrow. |

Thursday, November 01, 2018, 11:42, David Wang, Conditioning Station, Standard Operation, TM2, UCx 25., TM2 HS line helium pressure test at TCS and helium spray at SHC..
|
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray.
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there. The result is close to before. |

|
I did a leak check this morning on exit 2 module at TCS. LD base leak rate is 4.00XE-9atm.cc/sec, Base pressure is 0.00 X E-4 torr. All seals,
bellows, and flanges are checked. The new FC5 bellow is good. There is a big leak up to 2X E-6 atm.c/sec has been found on IG1S side panel . The panel
itself will be replaced this time. Machine shop is working on it.. Two small leaks in E-9 atm.cc/sec range have been found on the o-ring |

|
Cover 1 was removed from the exit module. Confirmed with David that the actuator rod that needed to be disconnected was the far left )as viewed by the
hot cell operator). The fastener for this rod was un-accessible from this side. Cover 1 was re-installed (two bolts left loose) and cover 2 was removed.
fastener holding the actuator together was removed and luckily it does have a remote start. |

|
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 |
