|
Monday, February 03, 2020, 09:10, David Wang, ITW, Standard Operation, TM4, , ITW TPs are switched off. started of ITW argon venting.
|
ITW is argon venting now.
Argon venting of ITW is done. It took about 4.0 to 4.5 hours to vent the ITW with 2-3 psi argon. The CG4 and CG4S showed 35 to 36 torr on epic
page when mechanical gauge is 760torr in electrical. Argon gas bottle is closed in electrical room. |
|
Thursday, January 30, 2020, 12:06, David Wang, ITW, Standard Operation, TM4, , ITW primary and secondary vacuum seals leak check.
|
Connected LD to ITW(TM4) TP1. Base LR 0.0Xe-9 atm.cc/sec. Base pressure 0.0Xe-4 torr. All ITW primary and secondary air to vacuum seals are helium spray
checked. There is a 5XE-9 atm.cc/sec leak on exit2 module top cover plate o-ring seal. The location is on west side, south corner of the plate.
Hi- vacuum resin are sprayed to leak area, and leak checked again. The leak is gone. The other seals on ITW vacuum vessel are good. |
|
Thursday, January 30, 2020, 10:22, David Wang, ITW, Standard Operation, TM4, , TM4 water lines helium pressure leak check.
|
TM4 internal water lines helium pressure leak check at ITW : 70psi helium 5 minutes on each circuits. Base leak rate 0.0X E-9 atm.cc/sec.
Base pressure 0.0X E-4torr. Only B line(Oven -) has a tiny 1.5Xe-9 atm.cc/sec response on LD during the check . All others all perfect good. |
|
Wednesday, January 29, 2020, 12:37, David Wang, ITE, Standard Operation, TM2, , ITE primary/secondary vacuum vessel leak check.
|
Leak check on ITE vacuum vessel is done. LD base leak rate 0.0XE-9atm.cc/sec. base pressure 0.0Xe-4torr. Sprayed helium on all ITE primary and secondary
vacuum vessel seals(including TM2). No leak . Also,70psi helium pressurized TM2 waterlines inside the module for each circuit 3 minutes. No leak
on all operating TM2 waterlines. |
|
Monday, January 27, 2020, 10:40, David Wang, Cooling, Maintenance, , , ITE/ITW supply water presuure on dump circuits.
|
With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi. I adjusted ITW dump pressure to 25 psi by changing the
return line side pressure relieve valve.
ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi. |
|
Friday, January 24, 2020, 08:19, David Wang, ITW, Standard Operation, TM4, , ITW water signal interlock check.
|
ITW water signal interlock check is done. Everything works fine. ITW 2A2 tank water signal is broken and is not ok on XT2A2 page. I will fix it
next week. |
