TM1 TiC #3 target  heat shield  helium pressure check  is done at conditioning station. Applied 80 psi helium to HS circuit for 5 minutes . There is no response had been found on leak detector. The leak detector base LR 0.0x E-9 atm.cc/sec, and BP 0.0xE-4 torr. CS and TM1 vacuum are at low E-6 torr range. The HS circuit is leak tight.

Chad and i did a leak check on TM1(Lp-TiC) heat shield water circuit at south hot cell. There is no leak had been found on it. The circuit  is leak tight at present. I will do  helium pressure check on this circuit at  conditioning station once the vacuum is good enough.

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.

TM1 has been connected in ITW. All turbo pumps are started. The pumping down on ITW is good so far. The water is supplied to TM1 for HV conditioning.

  783   Thursday, November 06, 2014, 08:55 David WangITWRepairTM1ThO#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 are from   one of  the connections  on primary BVs. I let Paul opened the BVs one by one,but the problem did not show again. Now ,the current draw on the turbo pumps are back to normal also.

I will keep monitoring the system and take a look on all KF25 clamps on BVs once I have a chance to access to ITW.

ThO#1 has been removed from TM1 and placed into the plastic dissection box.

Containment box cover has been reinstalled as per usual.
