Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3
of the 16 looked at were too hot to ship and assay. See attached pdf for complete details. |

Well the first of this year's lucky winners to win a fabulous one way trip to Chalk River are as follows. UC#1, UC#2, Ta#25, Ta#26, and Ta#37. First
these lucky winners will get to stay several days and night in the lovely all inclusive mini vault before being loaded in to their very own private F-308
flasks to be whisked away off to fabulous Chalk River. |

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to
storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini
storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for |

Monday, January 09, 2012, 14:44, David Wang, ITE, Maintenance, TM4, , ITE and TM4 2012 winter shut down leak check is completed.
|
I did a vacuum leak check on all ITE primary vacuum vessel and secondary vessel.I also did a helium pressure test(80psi ) on all TM4 water lines. There
is no leak has been found.ITE and TM4 are both leak tight now.

Tuesday, January 10, 2012, 11:51, Grant Minor, Conditioning Station, Repair, , , IMC at Cond. Station is VENTED - DO NOT PUT MODULE IN
|
Hi Remote Handling,
The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should
be reading about -20inHg and the bellows should be contracted (i.e. compressed). |

Thursday, January 12, 2012, 08:43, Travis Cave, Spent Target Vault, Standard Operation, , , Spent targets to F-308s
|
All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January
10th and the flasks were moved to rad waste on January 11th. Contamination was found on the bottoms of some of the pails and was removed, some of
the contamination was difficult but not impossible to remove from the pail bottoms. |

Thursday, January 12, 2012, 14:32, David Wang, ITE, Repair, TM4, , TP2 on TM4 has been replaced
|
TP2 on TM4 has been replaced with a new turbo pump , I didnt reset the controller in electrical room.So this new pump start to run at 8083 hours
on ITE TP2 controller. The new TP2 pump properly started. It works fine now. |

Monday, January 16, 2012, 09:30, David Wang, ITE, Maintenance, , , Changed all old inducion coils for flow sensors in ITE
|
I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very
stable and constant.All ITE inductions coils work fine now. |

Wednesday, February 01, 2012, 09:54, David Wang, ITW, Maintenance, TM1, , ITW and TM1 winter shut down vacuum leak check
|
ITW and TM1 winter shut down vacuum leak check had been finished yesterday.All ITW primary vacuum vessel, secondary vacuum vessel, and TM1water lines
had been leak checked.No any leak has been found .The ITW and TM1 are both leak tight.Some detail information below:
TM1 and ITW primary vacuum vessel and water lines: The leak detector was hooked on BV2 after TP2. Calibrate leak detector.leak |

Monday, April 02, 2012, 08:17, David Wang, Conditioning Station, Development, , , conditioning station IMC pump down.
|
I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The
bellow is in retracted condition now. |

Tuesday, April 03, 2012, 12:11, David Wang, Conditioning Station, Development, , , leak check on conditioning station vacuum system
|
I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the
convectron gauge reading on emittance box is 20m torr which is reasonable. I hooked the leak detector to system (without turbo pump on)
. The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, |

Thursday, April 12, 2012, 14:40, David Wang, Conditioning Station, Development, TM1, , conditioning staion and TM1 is under TP1 and TP2 pumping now.
|
TM1 moved to conditioning station to today. After moving, I connected the vacuum system which include all gauges ,vacuum lines , controllers,and fans.I
started roughing the station through two turbo pumps(on TM1) . After 2 hours roughing, the station vacuum went to 100 mtorr. I started TP1 and TP2 on TM1
and turned on 3 gauges (png1 on service cap, ig1 on service cap ,and png4 on emittance box) . All turbo pumps and high vacuum gauges work fine .The |

Thursday, April 26, 2012, 09:23, David Wang, ITE, Repair, TM4, , changed flow wheel on ITE TM4 contaiment box water circuit
|
The the magnetic field on ITE TM4 flow wheel was gone yesterday.So there is no water signal on this circuit. The water flow is fine ,and the wheel
is rotating. I removed 1 shielding block on ITE and replaced the old wheel with a new one.Now the containment box water signal is normal.The problem is
fixed.The shielding block is back. |
|
Thursday, April 26, 2012, 13:01, David Wang, ITE, Repair, TM4, , Replaced TM4 EE water flow wheel in ITE.
|
Due to weak magnetic field on TM4 EE water flow wheel, we have two times intermittent water signal on this circuit this morning. I replaced the old
wheel with a new one in ITE. I checked the signal frequency and strength.It looks fine now. |
|
Wednesday, May 02, 2012, 11:27, David Wang, ITW, Standard Operation, TM1, , 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. |
|
Tuesday, May 08, 2012, 10:28, David Wang, ITE, Standard Operation, TM4, , Disconnected TM4 in ITE.
|
I disconnected TM4 in ITE. The heat shield water circuit is purged. I closed the water supply to ITE.Now, the water system only supply water to
ITW and the system pressure is 110 psi which is good.I visually checked S-tank sight glass,and the water level is stable comparing to last week. Also,
I visually checked the ITW water signals strength and stability on electrical panel from electrical room.Everything looks fine. |

|
Five targets were moved to the mini storage today in preparation for transfer of the targets to the F308s later next week. The moves went well. See the
attached files for the vault and mini storage details. |
|
Monday, May 28, 2012, 13:05, David Wang, ITE, Standard Operation, , , I moved 5 shielding blocks from ITW to ITE .
|
5 shielding blocks have been transferred from ITW to ITE. ITE ventilation is opened, and ITW closed. All ITE water signals have been
checked for frequency and strength.They are all good. ITE is ready for taking proton beam. |
