No Source Tray installed. Loop on cooling circuit D. All other circuits blanked off.
Voltages stated below are set point voltages. These corresponds reasonably well with the local read backs on the power supplies. The read back
voltages in EPICS are somewhat lower. |

|
No leak detected on either He-detector (connected directly to Service Cap) or on RGA. See attached screen shots.
A vacuum increase (air only on RGA) was seen when de-pressurizing circuit I. |

|
At CS, The leak detector is hooked directly to the TM2 top service cap. The base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4torr. Applied 80 psi helium
to TM2 tube heater +(D) line . During 3 minutes applying time , I did not see any tiny change on LD readings. The line is perfectly vacuum sealed.
See attachment pictures. |

Friday, December 05, 2014, 07:47, David Wang, Conditioning Station, Development, TM2, , TM2 at CS
|
The pumping down on TM2 at CS was good overnight. However, the back up line pressure is still too high for LD to get to 0.0-E-9atm.cc/sec . It only could
get to 1.2xE-7 atm.cc/sec. It is not enough for a good leak check . I dont want to have any ambiguous situation on this" D" line leak check.
So,I am going to reconfigure the leak detector to the spare KF25 pot on the TM2 service cap. All pumps are stopped . The CS and TM2 will be vented soon. |

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 |
