Monday, March 21, 2016, 10:25, David Wang, Conditioning Station, Repair, TM2, , TM2 Helium pressure Test Result in TCS and ITW
|
TM2 has been helium pressure tested in ITW and TCS. They are both tested with 70psi helium, each circuit for 3minutes.
The leak detector base leak rate: 0.0X E-9 atm.cc/sec, base pressure 0.0 xE-4 torr for both ITW and TCS. The test results are:

Monday, March 21, 2016, 15:27, David Wang, Conditioning Station, Repair, TM2, , TM2 has been disconnected at TCS
|
| TM2 vacuum system has been disconnected at TCS. Venting is in process now. |

Wednesday, March 23, 2016, 11:32, David Wang, South Hot-Cell, Repair, TM2, , TM2 Helium spray leak check on GE and MSP lines at SHC
|
Chad and I did the helium spray leak check on TM2 GE and MSP water lines at SHC this morning. We confirmed the GE leak on water blocks. We can
not found the MSP leak by using the helium spray since its leak rate in TCS is much smaller than GE leak. The leak check process are as below:

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. |
|
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:

Wednesday, March 30, 2016, 15:49, David Wang, Assembly/Bench Test, Repair, TM2, , TM2 Helium spray leak check on solder stems inside service cap on the top of SW silo. 7x
|
On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected
to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems
for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak |

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. |

Monday, April 04, 2016, 11:14, David Wang, Conditioning Station, Standard Operation, TM1, , Helium pressure test on TM1 HS line at CS
|
| New UCx target is installed on the module. 70psi helium,3 minutes. NO response on LD. LD is pumped to bottom LR and LP during test. |
|
Tuesday, April 05, 2016, 12:36, David Wang, ITW, Standard Operation, TM1, , TM1 vacuum system has been connected in ITW.
|
| All turbo -pumps are started. |
|
Tuesday, April 05, 2016, 12:40, David Wang, ITE, Standard Operation, TM4, , I stopped ITE turbo pumps this morning
|
| The ITE and TM4 have been vented with Argon . TM4 vacuum system is disconnected in ITE. |
|
Friday, April 08, 2016, 07:10, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 vacuum has been connected in ITE.
|
| All turbo pumps are started yesterday. The pumping down is good over night. |

Friday, April 08, 2016, 08:13, Anders Mjos, ITE/ITW Cooling, Maintenance, , , High Active Water Resistivity
|
The high active water resistivity took a long time to recover after the upgrade to the water cooling circuit. The system needed about a month (from end
February to end March) to recover to nominal values. See attached plot of archiver data.
TM1 has now been connected in ITW and the water resistivity remains > 8 MOhm cm, which should allow normal operation. However, the resin is |
