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 detector BL 0.0xe-9atm.cc/sec,BP0.0xe-4 torr.

Sprayed helium to all primary vacuum vessel seals, flanges, turbo pumps,gauges, blank offs, bellows, and insulation blocks on TM1 and ITW. No any response had been found on leak detector.Also applied 60 psi helium to all water lines in TM1 for 5minutes each,no any response on leak detector.The leak rate stayed at 0.0xe-9 to 0.3 xe-9 atm.cc/sec all the time. All waterlines in TM1 are leak tight.

ITW secondary vacuum vessel:the leak detector was hooked on BV4s after TP4.Leak detector BL 0.0xe-9 atm.cc/sec ,BP 0.00xe-4 torr.  Sprayed helium to all secondary vacuum seals which include all bellows, tank to tank flange seals,tank flange to modules seals,beam diagnostics, gauges,turbo pumps, and EXIT 2 top service cap seals.No any response had been found on leak detector during the check. The secondary vacuum vessel is leak tight on ITW. 

All high vacuum gauges were read at 2-3xe -7 torr range  during the test time and no change during the test.

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.

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.

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.

  68   Tuesday, January 10, 2012, 11:51 Grant MinorConditioning StationRepair  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).

I've attached a photo of what the guage and fittings should look like when pumped down to -30inHg.

Either the IMC circuit has been vented, disturbed, or it has some kind of leak.  When I was in the Target Hall this morning, I saw the gauge bent around the railing at an awkward angle with a pretty severe bend in the copper line, it appeared to have been disturbed by the temporary glove box sitting at that level used by Rob Walker for nuclear ventilation work.

I will co-ordinate pump-down and leak check of the circuit, but the Conditioning Station cannot be used until this is repaired.

Cheers,

Grant

  67   Monday, January 09, 2012, 14:44 David WangITEMaintenanceTM4 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.

ITE primary vacuum vessel and TM4 waterlines:

Hooked leak detector after TP1 between BV1. leak detector base pressure :0.0xe-4 torr. base leak rate:1.8x e-8 atm.cc/sec.sprayed helium around all TM4 and exit 1 ,2 module primary vessel including all flanges,  gauges, bellows,turbos,blank offs,etcThere is no  any response  on leak detector. All water lines  had been pressurized with 80 psi helium  for 5 minutes. The leak rate always stayed at 1.8xe-8 atm.cc/sec which is the base leak rate  on ITE this time, and no vacuum pressure change also.The TM4  water lines and ITE primary vacuum vessel are leak tight.

ITE secondary vacuum vessel:

Hooked leak detector after TP1S between BV1S. Leak detector base pressure :0.0xe-4 torr.Base leak rate:0.0xe-9 atm.cc/sec. Sprayed helium around all TM4,EXIt 1,2  module secondary vessel including alll flanges,gauges, air cylinders , valves, and blank-offs.There is no any response on leak detector . tThe late rate  kept at 0.0XE-9 ATM.CC/SEC, and no pressure change either.The ITE secondary vacuum vessel is leak tight.

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 the status of both vaults.

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.

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.

  61   Tuesday, November 22, 2011, 15:07 Bevan MossConditioning StationStandard OperationTM1UCx #3HV testing

 High Voltage (HV) testing was completed on TM1 today. Vacuum was very good 1.9 x 10^-7 T in the service cap, 3.2 x 10^-7 in the containment box, and 2.0 x 10^-6 in the secondary. The voltage was successfully brought up to 27kV with a current draw of 0.12mA and o sparking. At the next step, 30 kV, the current draw was above 0.3mA and sparking was beyond 20 sparks per minute. The module should not be taken above 27kV. There is the possibility this voltage can be increased with conditioning but it is very unlikely. See attached for a graph of the testing. These results are comparable to the results without the source tray (see previous elog)

 TM1 was high voltage tested without a target on November 16, 2011 with Don Jackson, Pierre Bricault, and Bevan Moss. The module was able to hold up to 25 kV but between that and 32 kV there was lots of discharge which could be measured in the vacuum. See the attached plot for the voltage current and sparks.
