Wednesday, November 18, 2020, 15:28, David Wang, South Hot-Cell, Standard Operation, TM2, Nb#6, electrical check and HS leak check.
|
Everything looks good. A still short to P before target installation. We will float P,Q as before on module top. |
|
Thursday, November 19, 2020, 09:00, David Wang, Conditioning Station, Standard Operation, TM2, Nb#6, Helium pressure check on TM2 HS line at TCS.
|
LD 0.0 Xe-9 atm.cc/sec , 70 psi helium 3 minutes. No leak. |
|
Tuesday, November 24, 2020, 09:37, Adam Newsome, ITW, Standard Operation, TM2, , Module Move

|
Tuesday, November 24, 2020, 12:56, David Wang, ITW, Standard Operation, TM2, Nb#9, TM2 has been connected in ITW
|
TM2 has been connected to ITW. Turbo pumps are stared. ITW pumping down is fine so far. |
|
Monday, January 18, 2021, 12:29, David Wang, ITW, Standard Operation, TM2, Nb#9, ITW vacuum and TM2 water lines leak check .
|
ITW primary and secondary vacuum vessel leak check are done. There is a 5XE-8 atm.cc/sec leak on Exit service cap NW side square panel. The leak is small. And, it is close to ITW TP3 so it is not affect ion beam line vacuum during operation. We will replace the seal on the panel later. The rest leak check on air to vacuum seals are good. TM2 water lines are pressurized with 70 psi helium. We did it 3 hours after water lines are purged. No leak was showed during the check.
2021-02-24th: The o-ring on exit 1 NW side square panel is replaced by David Wang and Frank Song. |
