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. The leak could be from water block which is same as other lines. I do not think this leak rate will affect the operation.
The attachment can not be opened for some reasons. Please check TM2 leak check 2017-03-13 e- log for last time test result and comment. |

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. |

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. |

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 brakes work fine. |

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.
2017-08-03. Helium pressure test on TM2 HS line at TCS is done. 70psi helium, 3 minutes. base leak rate 0.0xE-7 atm.cc/sec. Result: 1.8XE-7atm.cc/sec leak which is almost same as before. This line has a very small leak on water block seal under helium pressure test which we knew already. |
