Thursday, March 24, 2016, 13:15, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 and TCS vacuum system has been connected
|
TM1 and TCS vacuum system have been connected. All turbo-pumps are started. The pumping down is fine. |
|
Thursday, March 24, 2016, 13:55, Travis Cave, Conditioning Station, Standard Operation, TM1, no target, module moved
|
TM#2 has been moved from the south hot cell to the south west silo and TM#1 was moved from the north east silo to the conditioning station. All done by 10AM. |
Tuesday, March 29, 2016, 08:38, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 water lines helium pressure check at TCS 
|
TM1 water lines helium pressure check at TCS is done. 70 psi helium was applied to water circuits. Leak detector base leak rate 0.0 x E-9 atm.cc/sec, base pressure 0.0 x E-4 torr. The result shows as below:
| Ta+ |
0.0 X E-9 atm.cc/sec |
3minutes stabilizing |
| Ta- |
0.0 X E-9 atm.cc/sec |
3minutes stabilizing |
| Tube- |

| MSP |
0.0 X E-9 atm.cc/sec |

| EE |
0.0X E-9 atm.cc/sec |
3minutes stabilizing |
| HS |
not tested without caps. |
|
| Window |
E-5 range,leak on stem as we knew before. |
10seconds to E-5 |
The results is good so far as we know the window line is leak on stem in service cap. The HS will be tested later with target on.
The service cap air to vacuum seals also have been checked. The PNG1 panel and side round panel close to shutter are leak. The o-rings on them need to be replaced.
On March 30th -2016, I doubled checked the air to vacuum seal on the TM1 service cap. The side round panel is leak free actually. The PNG1 panel is leak at the bottom side. Confirmed.
On march 31th-2016, The o-ring(1-1/ 2275) on TM1 PNG1 side panel has been replaced today. The o-ring slot and mating surfaces are cleaned, and new o-ring is installed. The panel is put back to TM1 and all bolts are tightened.

Friday, April 01, 2016, 13:58, Travis Cave, Conditioning Station, Standard Operation, TM1, UC#15, module moved
|
TM#1 has been moved from the conditioning station to the south hot cell, had UC#15 installed and then moved back to the conditioning station. |
|
Friday, April 01, 2016, 14:41, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 and TCS vacuum system has been connected. TCS control page white out.
|
I can not start the TCS pumps due to control page white out. Control group is working on this issue.
Control group fixed the white out problem. I started all turbo-pumps. The pumping down is good so far. The TM1 IG1 is broken. I will check it on next Monday. It could be a broken filament. Then, the filament will be replaced. |

Thursday, April 14, 2016, 09:46, Anders Mjos, Conditioning Station, Standard Operation, TM2, , TM2 water leak test
|
Thursday, April 14, 2016, 07:50: RGA on
Friday, April 15, 2016, 08:09 : Ratio between water and air is higher than normal (indicating possible air leak). See attachment. 3.5 more H2O than N2. (Ratio in TM3 Nov 2015 was 82:1)
A leak was found on the o-ring between the module flange and TCS. This could be fixed by cleaning the o-ring and sealing surface. The Window line is not closed and was accidentally pressurized with He on April 25
Tuesday, April 26, 2016, 08:47: David started the water package.
Wednesday, April 27, 2016, 08:15: Switched off chiller / water cooling.
Wednesday, April 27, 2016, 14:41: Switched chiller / water cooling back on. |
