| Subject: |
helium pressure test on TM2 tube heater +(D)and -(C)water lines. |
|
|
- TM2 installed in Conditioning Station
- Varian Leak detector connected directly to Target Module 2 Service cap.
- Vacuum draw in Target Station with both module turbo pumps
- Leak detector baseline normal (10^-4 Torr, 10^-9 Std cc/s He)
- Since no Source tray is installed, and tube heater supply conductor is blanked off in target enclosure, it was necessary to test both supply and return points.
- For each line tested, 80 psi He was connected, and waited ~2 min to for a response on the leak detector.
- Lines tested:
- conductor D (tube heater), Supply -> no He response
- conductor D (tube heater), Return -> no He response
- conductor C (tube heater), Supply -> no He response
- conductor C (tube heater), Return -> no He response
- Based on this leak testing, both supply and return lines of conductors C & D are leak tight under 95 psi He (80 psig He supply to vacuum)
