Wednesday, May 30, 2018, 09:51, David Wang, Conditioning Station, Repair, TM2, , TM2 water lines helium pressure test at TCS.
|
I did a helium pressure test on TM2 water lines at TCS. We will remove the TM2 source tray soon so this test is a reference check for future new source.
The result:
Helium 70 psi, 2 minutes to each circiut. Leak detector base LR.0.0x e-9atm.cc/sec, base pressure 0.0x e-4torr |

Leak detector is connected to ITW TP4. LD Base leak rate 0.0XE-09 atm.cc/sec. Helium line is connected to existing window leak check 1/8 " copper
tube. Applied 18psi helium for 1 minute. No response on LD. The window seal is good on ITW vacuum vessel. |

Anders and I leak checked new 2A2 window seal on ITW side. Leak detector was connected to ITW TP4. Base leak rate 0.0Xe-9 atm.cc/sec.
base pressure 0.0xe-4 torr. Sprayed 15-20 psi directly underneath 2A2 window by using exist 2a2 window leak check copper tube. The leak detector
got response in 5 seconds when helium was applied. the leak rate was 5xe-6 atm.cc/sec. Once the helium source was closed, the leak rate dropped quickly |
