 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 |

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.

|
| Argon vent and disconnect TM4 at TCS. |
|
Friday, September 08, 2017, 14:08, David Wang, Conditioning Station, Repair, TM3, , TCS and TM3
|
TM3 is located at TCS and it is pumping down now. TCS water system has been started. All TCS water lines for TM3 module internal cooling are bypassed
and looped at TCS top ground plate. Water only supply to TCS high current conductors. |
|
Wednesday, September 13, 2017, 10:05, David Wang, Conditioning Station, Repair, TM3, , Switch off TCS water system and vacuums
|
