Chad and i did a leak check on TM4 heat shield circuit with installed dummy target at SHC today. The leak detector is pumped to 0.0xE-9atm.cc/sec.Chad sprayed helium twice on each  VCR joints .There is no any response had been found on the leak detector during each 45 seconds waiting time. The TM4 heat shield circuit with dummy  target is leak tight so far.

Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o leak detector.

All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak  tight.Chad sprayed helium on each VCR joints for 2 seconds every time. During 1min waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 1minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM4 is in CS and under vacuum.

Chad and I did the TM4 heat shield leak check yesterday at SHC. The leak detector was pumped to 4.6 xE-9atm.cc/sec, and 0.0xE-4 torr after 1.5 hours pumping. Chad sprayed helium twice on both VCR fittings. There is no response had been found during each 45 seconds waiting time. Since the module moved to ITE directly,we didnt have helium pressure test this time. I  would say thee heat shield circuit is leak tight. so far.
