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. |
|
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. |
|
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. |

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. |
|
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. |

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. |

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. |
|
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. |

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, |

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

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. |

Monday, April 16, 2012, 16:17, Bevan Moss, Conditioning Station, Standard Operation, TM1, No Target, High Voltage Test
|
A high voltage test was completed on a target free TM1 in the conditioning station. Only the turbo pumps on the target module were operational
due to phase 2 construction. Testing started at 2:51PM with the following vacuum gauge readings, 1.6 x 10^-6 Diagnostics Box, 7.4 x 10^-7 Service Cap,
2.0 x 10^-6 Containment Box. Voltage was increased ~3kV at a time every minute until 21 kV was reached with a current of 0 uA. Voltage was then increased |

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 |

|
| TM#1 has been moved from the NE silo to the Conditioning Station. |
|
Thursday, April 05, 2012, 10:30, David Wang, ITE, Standard Operation, TM4, , I moved 5 shielding blocks back to ITE this morning.
|
| MAA is secured .The ITE and MAA are ready for taking proton beam 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, |
