Electrical check of TM#4 with SiC#29 attached. Results are pretty much the same as yesterday for the coil to 60kV common, and anode to 60kV common. See
attached pdf for details. |
Thursday, July 25, 2013, 10:08, David Wang, Conditioning Station, Standard Operation, TM4, SiC #29, TM4 HS helium pressure test andTM4 connection at CS
|
Bevan and I did a helium pressure test on TM4 HS water circuit at CS. The leak detector is pumped to the bottom scale(E-9 atm.cc/sec and E-4torr). We
applied 70 psi helium to the HS circuit for 3 minutes . No response had been found. I also leak checked IG1 flange which was replaced yesterday.
It is good. We connected the TM4 to CS and put the HV cover on. The water cooling system will be started soon. |
Monday, August 26, 2013, 18:26, Grant Minor, Conditioning Station, Standard Operation, TM3, , TM3 moved from Hot Cell to Conditioning Station
|
Target Module 3 with no target, and a partially-installed Rev-3 source tray (no steerers connected, no IMG connected, entrance window lines blanked off
on module side and not connected to containment box) was transported successfully to the Conditioning Station by Travis Cave and David Wang at around 4pm
today. David attached the vacuum system for start of pump-down to prepare for leak checking. |
Tuesday, August 27, 2013, 17:18, Grant Minor, Conditioning Station, Repair, TM3, no target, TM3 Rev 3 source tray - prelminary leak check results at CS
|
David Wang started a helium leak check on TM3 at the CS this morning.
David will create an e-log once his check is complete, but here are the preliminary results:
- target oven +/- OK |
Wednesday, August 28, 2013, 14:25, Travis Cave, Conditioning Station, Standard Operation, TM3, no target, module move
|
TM#3 with no target has been moved from the conditioning station to the south hot cell. The fields observed around the containment box of the module
ranged from 0.80 mSv/hr to 1.8mSv/hr.. |
Thursday, August 29, 2013, 06:48, David Wang, Conditioning Station, Development, TM3, , TM3 leak check in CS with new source tray.
|
A huge leak had been found on HS circuit during 60 psi helium pressurize test. Other circuits are free of obvious major leak at present .We will test
them again once the TM3 is back to CS. See attachment for details |

TM#3 with no target has been moved to the conditioning station from the south hot cell. |
Wednesday, September 11, 2013, 13:43, David Wang, Conditioning Station, Development, TM3, , Started 3 turbo pumps on CS for TM3
|
TM3 has been connected in CS.Three turbo- pumps have been started. The pumping down is fine so far. |
Friday, September 13, 2013, 07:49, David Wang, Conditioning Station, Development, TM3, , TM3 water lines leak check at CS
|
I leak checked TM3 water lines at CS with 60 psi and 80psi helium. The base leak rate is 5.0xe-9 atm.cc/sec. Each circuit 3 minutes helium pressurizing
for each time test. No any respose had been found on leak detector during the test. See attachment |

Thursday, September 26, 2013, 09:46, maicodallavalle, Conditioning Station, Repair, TM3, , Leak check / Pressure Test
|
TM3 has had all of the water lines pressurized with Helium and the Helium Leak detector was connected to the turbo pumps. There were no leaks detected. |

Thursday, September 26, 2013, 14:47, Bevan Moss, Conditioning Station, Maintenance, TM3, NiO#2, Water pumps turned on
|
The water pumps for the conditioning station were turned on at ~11:45. It took longer to start the conditioning station as the air from the leak
test had to be bled off and the make up water tank refilled. The valves on the water supply line were closed slightly to make up for the fact the water
cooled power supply has been removed. DIF2 was installed by Maico so we can measure the flow in the primary side. |
Thursday, September 26, 2013, 14:55, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, HV conditioning
|
The first attempt at HV conditioning of TM3 with the new source tray and NiO#2 target installed. Conditioning so far has been very slow, with the
current increasing quickly to a maximum of 400uA. Voltage in these cases was lowered until the current was below 200uA. Attached is the raw data. It appears
the source tray and target are conditioning just there is either something burning off or there is localized poor vacuum. |
Thursday, September 26, 2013, 15:00, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, RGA not connecting
|
Following the helium pressure test Don attempted to connect to the RGA via the network. He was unable to do so. This scan was desired so a pre
and post water scan could be compared to indicate if there was any leaking. It has been decided to carry on as the HV and HP tests are of greater importance.
Don will continue to investigate the RGA. Travis inspected from the conditioning station roof and determined that the RGA is getting power. |

TM#3 with NiO#2 has been moved to the south hot cell from the conditioning station. |
Friday, September 27, 2013, 12:53, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, HP TGHT and TBHT conditioning
|
Yesterday TM3 had the TGHT current raised to 160 amps and the TBHT raised to 200 amps. At this power the TGHT showed typical results in that vacuum
was affected and the increased voltage as the target increased in temperature. The tube heater on the other hand did not change voltage or show a change
in vacuum. As a result it is believe there is a short somewhere in the module. I have attached a screen shot of the strip tool and the raw data. |

|
The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down. |
