|
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 |
