 Wednesday, June 07, 2017, 13:33, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 SiC#36 leakc check and electrical check. 
|
| The results are good. See attachment. |

Wednesday, June 07, 2017, 13:34, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected.
|
| I started all turbo pumps. |

Thursday, June 08, 2017, 07:37, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 water llines at TCS.
|
The helium pressure test on HS line is done at TCS
this morning. I got the same result as last time when we helium pressure it it with first target in April. The leak rate on this line is 1.8 XE-7atm.cc/sec.
So, we know this leak is mostly on the line, but not on the VCR joints connecting the target. See attachment for last time(April) checking e-log. |

Thursday, June 08, 2017, 08:35, David Wang, Conditioning Station, Development, TM2, , TM2 gas line reconfiguration on the module top.
|
Reconfigured TM2 gas line on the module top. It matches with the febiad gas line we are using on service tray now. Facing the module, both of them should
be that right side line of two SST lines on feed-through. The gas line on TM2 was leak checked with a blind cap installed on service tray side and LD connected
on module top this Tuesday. It is leak free with helium spray on the top of module and service tray. |
|
Tuesday, June 13, 2017, 13:41, David Wang, ITW, Standard Operation, TM2, , TM2 has been connected in ITW.
|
Yasmine and I connected TM2 in ITW today. the control page is set to febiad mode. Both gas line in ITW are opened for febiad run. All connections are
double checked. Module connection checklist is finished. All turbo pumps are started now. Everything is good so far. The TM2 is ready for conditioning
when the ITW vacuum is good enough. |

Friday, June 23, 2017, 12:08, David Wang, Crane, Repair, , , TH crane inspection and probem fixing by Gordon crane
|
Gordon crane technician Peter came in today and checked TH crane. Maico and I were there with him. What he found is that brake gap on both side of
main hoist decreased after months of using. The solution is to lock the automatic self adjustment system so the gap will be fixed there. Each year
during annual inspection, they will adjust the gap manually. After he locked both side of device, I tested the crane up and down couple of times. The |

|
LD base LR:0.0Xe-9 atm.cc/sec. No leak has been found during the check. The HS line will be helium pressurized at TCS this week.
Helium pressurized the HS line at TCS. 70 psi 2 minutes, 0.0 x E-9 atm.cc/sec. No leak. |

Tuesday, June 27, 2017, 14:34, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 vacuum has been connected at TCS
|
| Turbo -pumps are started . The vacuum looks good so far. |
|
Wednesday, June 28, 2017, 10:00, David Wang, Conditioning Station, Standard Operation, TM4, Ta#52, TM2 has been connected at TCS
|
| I started TCS water system. |
|
Thursday, June 29, 2017, 11:55, David Wang, Conditioning Station, Repair, , , TCS HV cable and feed through installation
|
John Chow and I installed new TCS HV cable and feed through with their mounting panel back to TCS Faraday cage this Tuesday. ECO-4269 has been issued
for the new cable feed through and mounting panel. |

Wednesday, August 02, 2017, 15:09, David Wang, ITW, Standard Operation, TM2, , TM2 was disconnencted in ITW yesterday.
|
| Tm2 was disconnected in ITW yesterday. ITW EL cable crimp ring was broken. John Chow replaced this ring this afternoon. |
|
Wednesday, August 02, 2017, 15:13, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on HS line.
|
HS line is leak checked at SHC this afternoon by helium spay. Leak detector base LR 0.0 XE-9atm.cc/sec. Base pressure 0.0Xe-4 torr. No leak has
been found. This line will be helium pressured at TCS. It had a 1.7XE-7 atm.cc/sec leak rate on 70 psi helium at TCS during last two
target checks. |
|
Tuesday, August 29, 2017, 08:59, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 HS line leak checks
|
TM4 HS line leak checks are done, at SHC and TCS. SHC: Helium spray. TCS: Helium pressurize 70psi. LD base LR 0.0 X E-9 atm.cc/sec.
No leak has been found on both leak checks. |
