I moved 5 shielding blocks from ITE  to ITW.ITW is configured to take proton beam now.

  176   Wednesday, September 12, 2012, 11:59 David WangITWStandard OperationTM1UCxTM1 disconnected in ITW

I removed 5 shielding blocks from ITW to block storage area, and disconnected TM1 in ITW. After UCx run,  the radioactive level around the turbo pumps and primary vacuum lines are pretty high. This affect the general field inside the ITW pit around working area.i took 15 minuts to finish the job and i got 0.1msvr dose. the general field around my working area is about 350 usv/h.

Chad and i did a leak check on TM1 heat shield circuit with new Nb#7 target installed. It took about 5 mins pump down the circuit to leak rate 0.0x E-9atm.cc/sec and 0.0x E-4 torr on leak detector.

All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak  tight. Chad sprayed helium on each VCR joints for 2 seconds every time. During 45sec waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 45minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM1 is in CS and under vacuum.

Nb #7 was installed and tested today.

Inside face of the containment box cover was cleaned with methanol and a baseline picture taken in an effort to track deposits and marking as requested bty Anders.

  183   Wednesday, September 19, 2012, 11:23 Travis CaveSouth Hot-CellStandard OperationTM1Nb#7Electrical check

TM#1 with Nb#7 attached was electrically checked at the south hot cell yesterday, see attached pdf for details. Some notes about this test the oven to the 60kV common is 2Mohm this was noticed on the target prior to installation on the module, and the 60kV common to chassis is low at 874Mohm (low as in a non infinite value).

  186   Thursday, September 20, 2012, 09:16 David WangConditioning StationStandard OperationTM1Nb#7TM1 Nb#7 target heat shield helium pressure check is done.

Leak detector pumped down to base LR1.3xE-9 atm.cc/sec, and BP 8xE-3 torr. All high vacuum gauge readings at CS and TM1 are at low -6 range from 1.2xE-6torr to 4.6x E-6 torr. Applied 80 psi helium  to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit is leak tight.

TM#1 with Nb#7 moved from the conditioning station to the west target station. Move went well.

  188   Tuesday, September 25, 2012, 14:33 David WangITWStandard OperationTM1Nb#7TM1connected in ITW

TM 1 is in ITW now. All connections are done. The turbo pumps had been started this afternoon. The vacuum looks good so far. The water interlock check which related to TM1 are done. They are good. All TM1 water signals are visually checked and they are strong.  The rest interlock check ( MCR XT page) will be finished before shielding blocks moving. The MAA is locked and ITE is ready for proton beam.
