 Monday, February 17, 2014, 09:32, David Wang, Conditioning Station, Repair, TM2, , helium pressure test on TM2 tube heater +(D) water line. 6x
|
I did the helium pressure test on Tube heater+ line this morning. The vacuum on CS and TM2 are very good. The base lake rate on leak detector was 1.7xE-7
atm.cc/sec. Base pressure was 0.0xE-4torr. I applied helium to the "D"line .The test started from 30psi up to 80psi on both side "D"
line.The base leak rate slightly changed to 1.9xE-7 atm.cc/sec during the test,but not base pressure. At this base leak rate level, No obvious leak had |

Tuesday, February 25, 2014, 06:53, David Wang, South Hot-Cell, Repair, TM2, , Leak check on TM2 tube heater (+) water line with blank off(C-seal) installed on WB.
|
Chad and I did the leak check on TM2 tube heater (+) water line with blank off and C-seal installed on WB at South Hot Cell.The
line was easy to pump down to 0.0xE-9atm.cc/sec and 0.0XE-4 torr on leak detector. Chad flushed lot helium around the water block (10 sec spray). No response
had been found on leak detector. |

Tuesday, February 25, 2014, 10:00, David Wang, Conditioning Station, Repair, TM2, , helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on WB. 10x
|
I did the helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on water block at CS.The leak
detector was hooked directly to the top of the module this time. So base leak rate and base pressure were at the bottom scale on LD. 30 -80 psi helium
was applied to the D lines(both side) with10 psi increasing each time. There is no any tiny response hasbeen found during the test. The 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 |

|
Chad and I leak checked TM2 tube heater+(D) circuit at SHC with water bypass loop and new seals installed on the water block. The LD base LR 0.0xE-9
atm.cc/sec,base pressure0.0xE-4 torr. Chad sprayed helium on the leak check area in SHC for 5 seconds. No any response has been found on LD during 1minutes
waiting time. The test was repeated again and the result is same. NO LEAK at this stage! After the TM2 is moved to CS , The D line will be pressured |
