  128   Tuesday, June 19, 2012, 16:18 David WangITWStandard OperationTM1Ta38TM1connected in ITW

 We moved TM1 to ITW today, I connected TM1 to ITW, and started all turbo pumps this afternoon. TP4s is very difficult to bring to 38 KRMP now. I have to use soft start model and tried twice to get this pump started (1.5 hours). This pump always had a difficult start time during the past 2-3 runs. I talked with Friedhelm and we think it should be replaced after this run. I will issue an e-fault on this pump and try to get a new pump from vacuum group. It will take 2 hours to change this pump. I could do this job with another person help. Or, vacuum group could do it. Don can schedule a time for this job before next run. Anyway, it should work fine for this run.  The water interlock check related to TM1 is done. I will do the rest before blocks on. All TM1 water signals are strong and good. All vacuum gauge readings are good so far(below5.0xe-5 torr).

Starting at 11:00 am and finishing at 12:10 Ucx#4 previous target was removed and UCx#4 installed and leak checked on TM1.

During module move to the hot cell UCx#4 was housed in a bag under argon.

Chad and i did a leak check on TM1heat shield with UCx target on.The circuit are pumped  down to the bottom leak rate and base pressure is 3xE-3 torr on the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them   ( tested individually,2 seconds every time ) . The test repeated 1 time.There is no response on leak detector during 45 seconds waiting time on both time.Chad flushed helium around the target for 15 second. During 1 minutes waiting time , there is no response on leak detector.The heat shield circuit is leak tight at this stage. It will be helium pressure  in CS later.

TM#1 with UCx#4 has been moved from the south  hot hell to the conditioning station. No problems with the move.

TM#1 with UCx#4 electrical check done at the conditioning station under vacuum, see attached sheet for results.

Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG4 3.6 xE-6 Torr, IG1 1.1xE-6torr, IG4(diagnostic box) 3.4xE-6 Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 4 mins . There is no response on leak detector. The heat shield circuit is leak tight.

Connected TM1 in ITW,started 6 turbo pumps, and finished TM1 water interlock check . Every thing is good so far.

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.

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).
