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.

  112   Tuesday, May 22, 2012, 15:19 David WangITEStandard OperationTM4sic 27TM4 in ITE under pumping

  I started 6 turbo pumps this afternoon. The TM4 and ITE are under pumping now. The vacuum is fine so far. We will see a better picture tomorrow morning. In order to keep the system pressure at 90 psi, I just turned on all the water to TM4 circuits. The water interlock check which related to TM4 water circuits is all done. I will do the rest part (XTpage related to 2A beam) next week once I turn on all the water to ITE. The ITE and TM4 will be ready for HV conditioning once the vacuum is ok.

All TM4 connections in ITE is done. The station and TM4 is under roughing now.

Module has been moved from conditioning station to the east target station. Move went well.

  109   Tuesday, May 22, 2012, 10:00 David WangConditioning StationStandard OperationTM4sic 27helium pressure test on heat shield circuit

I did a helium pressure test on heat shield circuit. The leak detector is concected to the TM4 primary vacuum system.The IG1 is 1.1xe-6 torr,PNG4 is 1.5 x E-6torr,and IG4 is 2.1 XE-6torr.leak detector base leak rate:0.0xE-9 atm.cc/sec, base pressure is 0.0x E-4 torr.Applied 80psi helium to heat shield circuit for 4 mins .There is no any response on leak detector during 4mins time. There is no pressure change during the test time. The heat shield circuit is leak tight.

  107   Friday, May 18, 2012, 08:37 David WangSouth Hot-CellStandard OperationTM4sic 27leak check on heat shield circuit

Chad and I leak checked the heat shield circuit after sic 27 target  installed. It took 20minutes  to pump down the circuit to the leak detector bottom scales. The leak detector is calibrated today,and all the vacuum lines and connections are leak checked by spraying helium. Chad sprayed helium to each vc fittings for 2 seconds. There is no any response on leak detector . The test repeated one time and the result is same. Chad flushed  helium around the target for 10 second .This time leak detector also have no respone.  The heat shield circuit is leak  tight at this stage . We will move TM4 to conditioning station and pressure helium test the circuit.

SiC #26 was moved from the south hot cell into storage today. The target was is in pail # 94 and was placed in slot 1B in the storage vault. The fields of the pail at the hot cell were 118mSv/hr upon pail been removed from the hot cell. Attached is the current status of the storage vault.

  101   Tuesday, May 15, 2012, 12:14 chad fisherSouth Hot-CellStandard OperationTM4SiC#26SiC#26 removal TM4 degredation

SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.

Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray. I will again warn that the source trays historically have a life expectancy, and that TM4 continues to show visual signs that the current source tray is rapidly approaching the end of its useful life!

I understand that one of this years goals is to retrofit TM3; however I fear TM4(and possibly TM1) may fail before this can be released. With the current absence of backup source trays and modules I fear we leave the ISAC program in a very vulnerable position.

TM#4 with SiC #26 was moved from the East Station to the South Hot Cell. Bevan was at the helm of the PLC. There was no issue with the move.

  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.

  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.

  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.

  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.

  94   Tuesday, April 24, 2012, 10:38 David WangConditioning StationStandard OperationTM1 LP SIS Nb6TM1 heat shield circuit leak check with Nb5

 The pumping down on TM1 and conditioning station is fine over the weed end. The PNG 1(containment box) is 2.4xe-6 Torr, the IG1 (top service cap) is 9.0 xE-7 Torr, and the IG4 is 1.9xE-6Torr (diagnostic box). At this pressure, I connected the leak detector to the system and applied 80psi helium to the heat shield circuit. The leak rate and base pressure on leak detector are 0.0xE-9 Atm.cc/sec and 0.0xE-4Torr. There is no any response on leak detector during 4mins helium applying time. So the heat shield and Nb5 target water circuit is completely leak tight.
