  92   Tuesday, April 24, 2012, 10:02 Travis CaveITWStandard OperationTM1Nb#6module move

TM#1 with Nb#6 from the conditioning station to the west target station, move was uneventful. Mike LaRoss was there today for move in place of Don Dale working the PLC.

  97   Wednesday, May 02, 2012, 11:27 David WangITWStandard OperationTM1  ITW is ready for taking proton beam.

 I moved 5 shielding blocks from ITE to ITW .  I checked  all ITW water signals strength and frequency in electrical room, and everything looks fine.The ventilation system is set up for ITW. MAA is locked. ITW is ready for taking proton beam.

  116   Tuesday, June 05, 2012, 15:06 Bevan MossITWStandard OperationTM1Nb#6Module move from ITW to SHC

 TM1 has been moved from ITW to the SHC. The move did encounter some issues, one of the railings for preventing people from falling into the MAA was hit with the containment box. This caused the module to rotate. The module rotated ~90 degrees before the problem was noticed. The module was backed off from the post once noticed but had already freely rotated. The box was inspected with the cameras prior to being inserted into the SHC. No damage was detected. The error came as a result of over confidence. It did appear it was going to be hit but as the module moved closer I believed that there would be clearance. The angle of the camera has caused the module to appear it was going to hit thing before in the past but it actually (once the module was closer to the object) had several feet of clearance. This is not a mistake I will make again.

Chad Fisher, Grant Minor, and Don Jackson, have been alerted about this. Chad will complete another visual inspection in the hot cell. David will take swipes of the pole to ensure there is no contamination. 

  117   Wednesday, June 06, 2012, 08:21 David WangITWStandard OperationTM1 TM1 disconnected in ITW

I disconnected TM1 in ITW yesterday morning.The general radioactive level in ITW over the TM top (300mm) is about 350 usv/hr. contacting level on TP1 and TP2 are 1.0-1.2 msv/hr. I took 0.22 msv dose .The module is moved to

south hot cell later and a shielding plug is put back to ITW. Everything is fine.

  127   Tuesday, June 19, 2012, 10:35 Travis CaveITWStandard OperationTM1Ta#38module move

TM#1 with Ta#38 moved from the conditioning station to the west target station. Move went well.

  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).

 

  134   Monday, June 25, 2012, 14:39 David WangITWStandard Operation  I moved 5 shielding blocks from ITE to ITW,

and set up ventilation for ITW. ITW is ready for taking proton beam now. All water interlock checks for ITW are done. The ITW water signals strength and frequency had been checked from electrical room, and everything is good.

  151   Tuesday, July 31, 2012, 09:52 David WangITWStandard OperationTM1Ta38TM1 disconnected in ITW

I disconnected TM1 in ITW.  Heat shield line has been purged .

  159   Tuesday, August 07, 2012, 14:06 David WangITWRepair  ITW TP4S has been replaced

 I replaced ITW TP4S today as we scheduled. The working area is swiped and air sampled .Everything is fine.

The Series # of the old pump is 200927, and the new one is 600080. The E-fault 6081 which is related to the job will be closed.

  160   Tuesday, August 14, 2012, 11:16 Travis CaveITWStandard OperationTM1UCx#4module move

TM#1 with UCx#4 has been moved from the conditioning station to the west target station move went well.

  161   Tuesday, August 14, 2012, 11:16 Travis CaveITWStandard OperationTM1UCx#4module move

TM#1 with UCx#4 moved from the conditioning to the west target station move went well.

  162   Tuesday, August 14, 2012, 14:27 David WangITWStandard OperationTM1UCxTM1connection in ITW

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

  163   Monday, August 20, 2012, 12:28 David WangITWStandard OperationTM1 I moved 5 shielding blocks from ITE to ITW,

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

  164   Thursday, August 23, 2012, 07:34 David WangITWRepair  Replaced broken air lines on ITW HARP5B cylinder.

Prob guys replaced broken air lines on ITW HARP 5B Cylinder.Several shielding blocks had been moved out to make the cylinder accessible. After the replacement,the HARP5B works fine.All shield blocks had been moved back to original position. The job is done.

  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.

  187   Tuesday, September 25, 2012, 10:34 Travis CaveITWStandard OperationTM1Nb#7module move

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.        

  190   Tuesday, October 02, 2012, 11:47 David WangITWStandard OperationTM1Nb#7I moved 5 shielding blocks from ITE to ITW.

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