|
Some issues with the turntable and having to wait for a decision on whether to remove TM2 from the hot cell so that TM4 with dead UCx target could be
put in this morning.
Progress on TM2: |

|
Final polish, clean with methanol and clean compressed air.
Loop installed and torqued to 90 in lbs.
Minimum of approximately 1" between loop and containment box at closest point. |

Tuesday, December 02, 2014, 13:33, David Wang, South Hot-Cell, Development, TM2, , Leak check on TM2 tube heater +(D) at SHC
|
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 |

|
| I connected TM2 and CS vacuum system. All vacuum pumps on TM2 and CS are started .The pumping down is good so .far |
|
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. |

Friday, December 05, 2014, 11:58, David Wang, Conditioning Station, Development, TM2, , helium pressure test on TM2 tube heater +(D) water lines. 6x
|
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.
