I changed ITE dump water circuit flow wheel due to its poor performance. The new flow wheel works fine. The signal on electrical board is strong and constant. One shielding block on ITE was moved out for the job, and it has been moved back after the job.The ITE is ready to take proton beam. Travis was with me when i did the job.

I have inserted the test target for TM4 and the CS into the hot cell.

I had some concerns about the condition of the target which I have discussed with Pierre and he has cleared. Pictures are attached.

TM#4 has been moved from the SW silo to the south hot cell, move went well.

Bevan attempted to start pumping down on TM4 today remotely but there was an issue.  He will report on Monday.

I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:

- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise)

- Closed the VAT valve between the scroll pump and the nuclear ventilation

Attached are some photos of TM4 in the Conditioning Station after the no-module HV test completion.  Only vacuum services are connected.

  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.

the switches and the solenoid are all wire up to 24VDC, when you open either of the little doors the solenoid switches this is also true if there is a power loss. currently the solenoid is powered.

  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.

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

Bevan and I replaced TM4 TP1 today at conditioning station .The pump will be started this week when I do ITE and TM4 leak check .

  251   Friday, March 01, 2013, 11:35 David WangITEMaintenanceTM4 Leak check on ITE and TM4.
 The leak check on TM4 and ITE is done. All primary vacuum vessel , secondary vacuum vessel  on TM4 and ITE are leak tight. There is no any response had been found on leak detector(leak detector base LR 0.0xE-9 arm.cc/sec). All water lines had been pressurized to 70 psi helium for 3 minutes. They are all perfect leak tight( I cant find even a tiny response on leak detector) except GE water cooling line. On the GE water line, the leak detector got a instantaneous response once I applied the helium to the circuit.The leak rate climbed directly from 0.0xe-9 atm.cc/sec to 1.5 xe-5 atmcc/sec even if I stopped the helium pressurizing immediately. Once I purged the helium out of the line, the leak rate return to 0.0XE-9 atm.cc/sec quickly. I repeated the test on GE water line again and got exactly same result as the before. I would say the leak on the ITE GE water circuit isn't a small leak. The same test could be fulfilled once the TM4 is in CS later.

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