TM#4 with SiC#27 has had its electrical check. See attached PDF for details.

Entry  Friday, May 18, 2012, 08:17, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#27, SiC#27 Installed 

SiC#27 has been installed onto TM4. Fit was very good. All electrical connections double checked with mirror.

Entry  Thursday, May 17, 2012, 14:08, Travis Cave, South Hot-Cell, Standard Operation, TM4, no target, module move 

TM#4 has been moved from the north east silo to the south hot cell for target installation.  No problems with the move.

Entry  Wednesday, May 16, 2012, 10:35, Travis Cave, Spent Target Vault, Standard Operation, , SiC#26, Spent target move Vault_Storage_May_16_2012.pdf

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.

TM#4 moved from the south hot cell to the north east storage silo. No issues with the move.

Entry  Tuesday, May 15, 2012, 12:14, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#26, SiC#26 removal TM4 degredation 19x

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.

Results of the electrical check of TM#4 with SiC#26 attached post beam.

Entry  Monday, May 14, 2012, 12:37, Travis Cave, ITE, Standard Operation, TM4, SiC#26, module move 

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.

Entry  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.

Entry  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.

Entry  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.

Entry  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.

Entry  Tuesday, April 24, 2012, 10:38, David Wang, Conditioning Station, Standard Operation, TM1, LP SIS Nb6, TM1 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.

Entry  Tuesday, April 24, 2012, 10:36, Bevan Moss, Conditioning Station, Standard Operation, TM1, Nb#6, HV test April 23 

 A HV test was complete on TM1 with Friedhelm, David, and Myself. The module behaved as it has in other tests. The vacuum achieved was 1.6 x 10^-6 in the diagnostics box, 2.3 x 10^-6 in the containment box, and 8.6 x 10^-7 in the service cap. Maximum voltage without continuous sparking achieved was 27kV. Current was unstable varrying from 40 to 300 uA. This voltage was held for 10 minutes. 

Entry  Tuesday, April 24, 2012, 10:02, Travis Cave, ITW, Standard Operation, TM1, Nb#6, module move 

TM#1 with Nb#6 from the conditioning station to the west target station, move was uneventful. Mike LaRoss was there today for move in place of Don Dale working the PLC.

Entry  Friday, April 20, 2012, 14:07, Travis Cave, Conditioning Station, Standard Operation, TM1, Nb#6, module move 

TM#1 with Nb#6 is now in the conditioning station. The fields of the module at the south cell was 15.8mSv/hr. The move was uneventful. Don Dale was present for the move locking out parts of the code so only one movement of the crane could be done at a time.

Entry  Thursday, April 19, 2012, 09:48, David Wang, South Hot-Cell, Standard Operation, TM1, LP SIS Nb 6, leak check heat shield circuit 

Chad and I did a leak check on TM1 Nb5 target heat shield circuit. The leak detector was connected to heat shield circuit.The pumping down  of the  circuit is very smooth.Base leak rate is 0.0xE-9atm.cc/sec,and the base pressure is 0.0xE-4 torr. Chad checked the helium flow downstairs .He sprayed helium to both up and down VCR joints 2seconds each time. There is no any response on leak detector(30 seconds waiting time). Both joints did the same test twice, no response . Finally, he flushed helium around the target for 10 seconds,and i didnt see any response on leak detector either.The heat shield circuit on TM1 Nb5 target is leak tight at this stage.

Entry  Thursday, April 19, 2012, 09:36, Travis Cave, South Hot-Cell, Standard Operation, TM1, Nb#6, Electrical check Elec_Check_TM1_Nb6.PDF

Electrical check has been completed of TM#1 with Nb#6 attached. Our new micro-ohm meter was also used for the first time for this test.

Entry  Tuesday, April 17, 2012, 11:30, Travis Cave, South Hot-Cell, Standard Operation, TM1, no target, module moved 

TM#1 moved from conditioning station to the south hot cell, the module had a field of 16mSv/hr.  The move was not without excitement as the crane decided on its own to move 2 inches west on two occasions during the move.On the second time that the errant moved happened I hit the E-stop on the crane kill the power, the first time it happen it stopped the errant movement on its own.

Entry  Tuesday, April 17, 2012, 10:15, chad fisher, South Hot-Cell, Standard Operation, TM1, Nb#6, Target inserted into south hot cell 

Nb#6 has been inserted into the south hot cell in preparation for ionstallation onto TM1. During the pre-insertion inspection I noticed that I could see the foil installed into the ionizer tube and that in did not seem to be seated or concentric to the tube itself. I had Anders and Friedhelm check this and they deemed that it was ok.
