  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.

  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

  69   Thursday, January 12, 2012, 08:43 Travis CaveSpent Target VaultStandard 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.

  70   Thursday, January 12, 2012, 14:32 David WangITERepairTM4 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.

  71   Monday, January 16, 2012, 09:30 David WangITEMaintenance  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.

  72   Wednesday, February 01, 2012, 09:54 David WangITWMaintenanceTM1 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 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.

  79   Monday, April 02, 2012, 08:17 David WangConditioning StationDevelopment  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.

  80   Tuesday, April 03, 2012, 12:11 David WangConditioning StationDevelopment  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, and the cross tube flange to vessel. I found some of the bolts on the flanges could be tightened more ½ to ¾ turn without difficulty. I checked all the fasteners on the box, cross tube, and turbo pump, tightened some of them. By doing it, the base leak rate dropped to 3.0x E-8 atm,cc/sec, base pressure still 0.0XE-4 torr. I sprayed helium again, the response I found before now disappeared. I waited for about 1hour, and let the leak detector base leak rate dropped to 1.3 xE-8 atm.cc/sec, and base pressure still at 0.0xE-4 torr. At the same time, i only use leak detector as back up pump for whole sysytem and shut off the valve to the scroll pump.By doing this , the leak detector is much stable on the base leak rate. With the help of Bevan, i sprayed the helium to all the vacuum  equipments again.This time,no any tiny response has been found on leak detector.The leak rate stayed at 1.2x E-8atm.cc/sec, and no change on pressure also. I checked helium bubble several times during the spray. The conditioning station vacuum system is leak tight.

  81   Thursday, April 05, 2012, 10:30 David WangITEStandard OperationTM4 I moved 5 shielding blocks back to ITE this morning.

 MAA is secured .The ITE and MAA are ready for taking proton beam now.

  83   Thursday, April 12, 2012, 14:40 David WangConditioning StationDevelopmentTM1 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 pumping down of the station is smooth so far. With only 1 hour turbo pump on all three gauges readings are at low -5 torr range. The fans for cooling the turpump are also turned on. Everything is fine.

  84   Friday, April 13, 2012, 12:31 David WangConditioning StationDevelopmentTM1 TM1 and conditioning station leak check.

  I hooked up the leak detector to the TM1 and conditioning station vacuum system, and did the air to vacuum leak check on TM1 and station. The leak detector base leak rate 0.0x-9Eatm.cc/sec,base pressure 0.0x -4E torr. I sprayed helium around all water quick connectors (especially heat shield),gasline and valves, all gauges, turbo-pumps, bellow,  flanges, and blank-offs. There is no any response on leak detector. The TM1 is leak tight on air to vacuum seal. All   water lines on this module had been pressurized with 80psi helium when module was located in ITW on this January, and they are all leak tight. Bevan and I did a leak check on new installed diagnostic box and all vacuum lines, gauges, and turbo pump last week, and they are all leak tight. So I would say the whole vacuum system on TM1 and conditioning station now is leak tight. Right now, the PNG1(inside containment box ) is 6.5 xE-6Torr, the IG1 (top service cap which close to turbo) is 2.1xE-6 torr, and the IG4 (inside diagnostic box) is 4.1xE-6 torr.  

  95   Thursday, April 26, 2012, 09:23 David WangITERepairTM4 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.

  96   Thursday, April 26, 2012, 13:01 David WangITERepairTM4 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.

  97   Wednesday, May 02, 2012, 11:27 David WangITWStandard OperationTM1  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.

  98   Tuesday, May 08, 2012, 10:28 David WangITEStandard OperationTM4 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.
