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.

ThO#1 has been installed onto TM1 and is ready for leak and electrical checking. High current fasteners torqued to 130 in lbs.

TM#1 with ThO#1 electrical check see attatched PDF for details.

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 with ThO#1 is buttoned up and ready for transport.

TM#1 with ThO#1 has been moved from the south hot cell to the west target station.

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.

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.

Dan and I transferred 5 shielding blocks from ITE to ITW. The ITW is configured to take proton beam.

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

Containment box cover has been reinstalled as per usual.

TM#1 has been moved from the west station to the south hot cell had the ThO#1 target removed and then the modules was moved from the south hot cell to the south west silo. Also an electrical check was done on the target before it was removed.

Chad, Anders and Alex inspected the target this morning. The target had no significant visible damage to the container. Some material was deposited on the Extraction Electrode.

The ThO#1 has been placed in the storage vault placed in pail #122 in spot 2B of the vault. It was 6.2mSv/hr upon removal from the south hot cell. see attached PDF for details.

 TM#4 has been moved from the east target station to the south hot cell.

TM#1 with TaC#1 installed passed the electrical test. With a value of 882MOhms that was meggered from the heat shield to the chassis, all other measurements are within spec.

Move of TM#1 with the TaC#1 target has been moved from the south hot cell to the west target station.

TM#1 with TaC#1 from the west target station to the south hot cell. Move went well.

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.

Inspection of TM1 with the target removed yeilded no obvious signs of trouble, save a piece of capton tape found on the sliding tray directly below the service tray.

Inspection of TaC#1 showed that the oven was indeed broken on the A+ (left oven leg) side of the central block.

See the following for pictures.

TaC#1 was moved from the south hot cell to the storage vault. It was placed in pail#92 and put in vault slot 7B. It was 239mSv/hr upon removal from the south hot cell.
