TM#1 with TiC #3 moved from the conditioning station to the west target station,  move went well.

  214   Wednesday, November 14, 2012, 10:57 David WangITWStandard OperationTM1 TM1connected in ITW

I connected TM1 in ITW yesterday. Everything is good so far. Travis was with me when i did the job.

  225   Wednesday, January 02, 2013, 12:11 David WangITWStandard OperationTM1 I moved 5 shielding blocks from ITW to block storage area

I moved 5 shielding blocks from ITW  to block storage area for preparing the TM1 disconnection. Air sampled and swiped blocks and ITW and everything is fine.Fiona was with me all the time during the moving.

  226   Thursday, January 03, 2013, 10:05 David WangITWStandard OperationTM1 Disconnected TM1 in ITW.

TM1 has been disconnected in ITW. All  water lines had been purged. Travis was with me during the job.

  229   Thursday, January 10, 2013, 10:40 David WangITWMaintenance  Replaced all high active water system magnetic pedal wheels in ITW and ITE.

I replaced all high active water system magnetic pedal wheels in ITW and ITE. This is a preventive maintenance job we planned for this winter shut down.

  230   Monday, January 14, 2013, 14:09 Travis CaveITWStandard OperationTM1no targetmodule move

TM#1 has been moved from the south hot hell to the west target station, move went well.

  231   Tuesday, January 15, 2013, 10:49 David WangITWStandard OperationTM1no targetTM1 vacuum system connection in ITW

I connected TM 1 vacuum system in ITW. The TM1 and ITW will be pumped out for shut down routine leak check.

  240   Thursday, January 24, 2013, 13:30 David WangITWStandard OperationTM1 ITW-TM1 2013 winter shut down leak check.

2013 winter shut down ITW-TM1 primary vacuum vessel, secondary vacuum vessel, and water lines leak check: connected leak detector to TP2(primary and water lines) and TP4S (secondary). base leak rate 0.0xE-9atm.cc/sec,base pressure 0.0XE-4torr. Sprayed helium to all primary vacuum seal and there is no response on leak detector. Helium pressurized all water lines(except HS) at 70psi ,3mins.Tube heat(+) no response, tube heater(-)1.6xe-9atm.cc/sec, target oven(-)5.8xe-9atm.cc/sec, target oven (+) 6.9xe-9atm.cc/sec, EE 5.7xe-9atm.cc/sec, MSP no response, window 7.5 xe-9atm.cc/sec.All water lines are water leak free.  Two leaks had been found on secondary vacuum vessel. One is on exit 1 to tank o-ring (east side, E-N corner). The leak detector got   responses from 1.4 to1.7 xe-7 atm.cc/sec scale . The test  hadbeen repeated 4-5 times and   confirmed the location   . The second one is a small leak which  is on exit 2 to tank o-ring(east side, close to E-N corner). The leak detector got  responses from 1.4 to 1.8xe-8atm.cc/sec scale. The test had been repeated 3 times and confirmed the location. As the present plan. we will replace the exit1 to tank o-ring during this year shut down time.

  244   Thursday, February 14, 2013, 09:31 David WangITWRepair  ITH MP1 is replaced.

Edi and I replaced the broken ITH MP1 in target hall with a new pump. The old pump was leak on oil. There were no oil had been left in the old pump by checking the sight glass.Thats the reason of  the pump  failure.The tray which the old pump sat on was full of leaking oil ( highly contaminated ). The old pump was bagged in 3 thick plastic bags ,and the tray was cleaned before the new pump was installed. The working area had been cleaned up and surveyed couple of times after the job. Everything is good. The new pump had been tested after the installation. It works fine.

  245   Thursday, February 21, 2013, 14:05 David WangITWRepairTM1 Disconnected EXIT1 in ITW.

Disconnected EXIT1 in ITW. All cables , wires and air lines are label marked.

  248   Tuesday, February 26, 2013, 10:26 Travis CaveITWStandard OperationTM1 module move

TM1 moved from the west station to the southwest silo. Move went well.

  252   Wednesday, March 06, 2013, 10:09 Travis CaveITWMaintenance  module move

ITW EX1 has been moved from the west target station to the south hot cell for the seal replacement on the west station.

  254   Wednesday, March 06, 2013, 14:12 David WangITWRepair  ITW EXIT1 tank to module o-ring replacement
 ITW EXIT1 o-ring replacement is fininshed today. The ITW EXIT 1 is back to ITW. The old o-ring lost most its elastic property and changed to stiff sqaure shape inside the slot.The flange surface around the o-ring slot was dirty. I cleaned the o-ring surface completely before putting the new o-ring . Everything should be fine now. There will be a leak check late on this new installed o-ring.
  295   Friday, April 12, 2013, 10:27 David WangITWStandard OperationTM1 I reconnected TM1 to ITW.

TM1 has been reconnected in ITW. Water interlock check for TM1 is done.

  296   Friday, April 12, 2013, 10:32 David WangITWRepairTM1 ITW EXIT1 tank to module o-ring leak check.

I leak checked new installed ITW EXIT1 tank to module o-ring.No leak had been found . Also ,TM1 primary vessel air to vacuum seals had been checked at the same time. There was no response had been found on leak detector.

  331   Tuesday, May 07, 2013, 12:07 David WangITWStandard OperationTM1 I moved 5 shielding blocks from ITE to ITW.

Water interlock check  on ITW is done. All water signals are strong on EL panel.  ITW is configured to take proton beam.

  376   Tuesday, June 11, 2013, 10:05 David WangITWStandard OperationTM1 Disconnected TM1 in ITW.

Dan and I  disconnected TM1 in ITW.

  396   Thursday, July 04, 2013, 11:37 David WangITWStandard OperationTM1UCxI reconnected TM1 to ITW.

 I  reconnected TM1 to ITW on 02 July.The pumping down is good so far. TM1 water interlock check is good also.

  399   Tuesday, July 09, 2013, 14:26 David WangITWStandard OperationTM1UCx5 shielding blocks had been transferred from ITE to ITW

5 shielding blocks had been  transferred from ITE to ITW.  The  ITW is configured to take proton beam.
