|
Chad and I leak checked HS line on TM1 with ThO#1 target installed. The LD pumped down to base leak rate 0.0xE-9 atm.cc/sec, base leak rate 0.0xE-4 torr.
The pumping down process is normal. Chad sprayed helium on both VCR joints (each for 2 seconds) , and he did a flush spray around the target for 5 seconds.
No any response had been found on LD during and after the spray( 40seconds waiting time). The target is leak tight. |

Thursday, November 06, 2014, 08:55, David Wang, ITW, Repair, TM1, ThO#1, primary vacuum back up pressureITH CG1 ,CG2,CG4A were high.
|
I found primary vacuum back up pressure ITH CG1, CG2, and CG4A were unusually high this morning. They should be about 10 -20 mtorr after one night pumping,
but all of thier reading were 340-350-mtorr. Thease cause the current draw on primary turbo pumps were all over 2.0A(should be about 1.0A). I let Paul
closed all BVs on primary side . The pressure dropped quickly to normal range after all BVs were closed. This shows the back up line are good. The problem |

|
November 15, 2011 removed TaC#1 from TM1 and inspected TM1 for any obivous signs of trouble (Problems with EE at end of run).
Upon starting removal of the high current conductor fastener on A+ (Left oven leg) it became clear right away that the oven of the target was broken
as the leg moved as soon as the fasten was loosened. |

Chad and I did a leak check on heat shield circuit after target is installed on TM1.The leak detector pumping down is smooth. The base leak rate is 0.0xE-9
atm.cc/sec. The base pressure is 0.0xE-4torr. Chad checked helium flow downstairs and sprayed helium to each joints for 2 seconds.The first joints is good
and there is no any response on leak detector.we double checked it again and got the same result. On the second joint, Chad sprayed helium 2second. After |

|
TM1 was moved from SHC to the TCS. The mode took roughly 1 hour. During the move the north east corner of the containment box caught slightly on the
flange of the vacuum vessel and then slipped off. The contact was minimal but should none the less be noted. After sliding off of the flange the module
did not crash into the other sides of the vacuum vessel, this is why I believe the contact was minimal. It should be noted that the corner of concern is |
