Thursday, August 08, 2024, 13:58, David Wang, South Hot-Cell, Standard Operation, TM3, SiC #46, TM3 SiC#46 electrical check at SHC with target on (After operation)
|
ABCD is short to 60KV bias. Othjer are ok. see attachment.
Found afterwards that this short was due to sparking through the multipin wire insulation where the wires pass behind the TBHT block "C". See fault 17265. |

Monday, July 07, 2014, 14:45, Grant Minor, ITE, Maintenance, TM3, SiC #30, FEBIAD gas line check
|
There were some problems this morning with provision of FEBIAD gas to the the target at ITE. It was suspected that the gas line was improperly connected to the module, or that the valves at the module were not opened.
Remote Handling was asked to open the HV cover on TM3 at ITE and check the connection of the FEBIAD gas line. Grant Minor, Maico Dalla Valle, Dan McDonald, and Anders Mjos entered the Target Hall before lunch on Work Permit I2014-07-07-1.
Maico entered ITE with suit and respirator, disengaged / disconnected the interlocks and removed the HV cover. He inspected the FEBIAD gas line and found that it was properly connected, and that the valves were both open. The gas line is shown in the attached image, with both valves marked in red.
Grant and Anders went into the electrical room to examine the supply gas bottle and supply circuit, and found that the supply gas pressure to the regulating valve was low. It was concluded that the problem was not at the Target Module / Target Station.
Grant returned to the Target Station and instructed Maico to replace the HV cover. After this was done, Grant confirmed with Jon Aoki over the phone that the interlock switch signals were both reading "OK".
Friedhelm Ames made an entry in today's ISAC Ops e-log regarding the supply pressure to the regulating valve.

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. |

Thursday, July 24, 2014, 18:21, Grant Minor, South Hot-Cell, Repair, TM2, No target / no source tray, Leak check on TM2 ionizer tube cooling lines C and D - module side  
|
Target Ionizer tube cooling lines "C" and "D" in Target Module 2 were both leak checked at the Hot Cell. The lines were both blanked-off.
Bill Paley was present with David Wang in the Target Hall, operating the leak detector. Grant Minor and Anders Mjos were present with Chad Fisher at the Hot Cell.
The "D" circuit was already blanked off with a copper blank containing silver brazed stainless steel inserts and indium plated inconel c-seals.
The "C" circuit was already blanked off with an aluminum blank and rubber o-rings.
The cooling lines are indicated in the attached screencapture from ITA6021 Rev .14, and are also labelled in the attached photo.
The "D" circuit was checked first, starting at around 12pm.
1. The helium flow was tested by blowing dust on the work table.
2. The base leak rate on the Varian leak detector was confirmed in the "D" circuit to be stable at 10^-9 atm cc / sec and the pressure was 10^-4 Torr.
3. Each soldered joint on the "D" circuit was sprayed with a 2-second blast of helium - no response at the Varian.
4. The joint between the module-half of the water block and the copper blank-off was sprayed with a 2-second burst - no response.
5. A general area flood of helium sprayed for 10 seconds was applied all around both the "D" and "C" blocks - no response.
It was concluded that the "D" circuit had passed this leak check. The "C" circuit was checked next. The detector was changed to the "C" circuit and the circuit was pumped down. At around 2pm the leak check resumed.
6. The base leak rate on the Varian leak detector was confirmed in the "C" circuit to be stable at 10^-9 atm cc / sec and the pressure was 10^-4 Torr.
7. The solder joint area on the "C" circuit was sprayed with an 8-second burst of helium - no response.
8. The joint between the two halves of the water blocks was sprayed with a 6-second helium burst - no response.
It was concluded that the "C" circuit had passed this leak check.
The electrical continuity of the "C" and "D" circuits were confirmed in the Target Hall at the service cap, and in the module at the Hot Cell, to double check that the correct lines has been pumped and leak checked - this was OK.
The ionizer tube heater lines appear to be leak tight at the Hot Cell.
