The F-308 have been cleaned and serviced. There were three F-308's that came back with some contamination.#13, #15 and #19 were found to have contamination. They were decontaminated. All of the loose contamination was removed. There is still some fixed contamination. The levels of contamination are low enough to still be used for shipping spent targets. They have been moved to the north hot cell area and are ready for to be filled with spent targets.

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.

Five spent targets have been moved from the storage vault to the mini storage vault. The five targets are as follows: SiC #25, Ta #34, Ta #32, Ta #31, Nb #4. See the attached PDFs for full details.

Entry  Wednesday, November 21, 2012, 09:36, Travis Cave, Spent Target Vault, Standard Operation, , , Spent target move 

On Nov 20th the 5 targets in mini storage have been moved to the F-308s, those F-308s have since been moved to the hot cell ante room. They will sit there until Monday.

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.

Entry  Friday, January 18, 2013, 16:56, Grant Minor, Conditioning Station, Standard Operation, TM4, , VAT valve btwn roughing and nuc. vent. closed 

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

Entry  Thursday, January 24, 2013, 13:30, David Wang, ITW, Standard Operation, TM1, , 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.

Entry  Monday, January 28, 2013, 12:26, Travis Cave, Conditioning Station, Development, , , Switches connected 

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.

Entry  Thursday, February 14, 2013, 09:31, David Wang, ITW, Repair, , , 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.
