|
This Monday morning, Chad and I leak checked heat shielding circuit on TM3 with new target installed. The base LR on LD :0.0xE-9 atm.cc/sec, base pressure
0.0xE-4 torr. Chad sprayed helium twice on the VCR joints. No leak has been found. The circuit will be pressured with helium at CS. |

Tuesday, June 26, 2012, 14:10, David Wang, South Hot-Cell, Repair, TM3, , TM3 heat shield and window circuits leak check is done.
|
Chad and i did a leak check on TM3 heat shield and window circuits.Both circuits are pumped easily down to the bottom leak rate and base pressure on
the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them ( tested individually,2 seconds every time
) . There is no response on leakdetecor during 45 seconds waiting time. On window circuit there are 2 VCR joints. Chad sprayed helim on these joints(2seconds |

Friday, July 22, 2016, 10:57, David Wang, Conditioning Station, Repair, TM3, , TM3 has been moved and connected at TCS
|
I started vacuum system.
I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning. HV cover is installed
on TM3 in TH. The module is ready for HV conditioning. |

|
TM3 has been connected in CS. All water supplies are bypassed theTM3 on the top of the service cap. TM3 TP2 was difficult to start. It is started finally
after couple of time try.The pump runs fine now. |

Thursday, January 16, 2025, 14:21, David Wang, Conditioning Station, Standard Operation, TM3, No target, TM3 electrical check at TCS under good vacuum
|
A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter
check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern. The rest things are good.
See attachments. |

Tuesday, November 12, 2013, 09:51, David Wang, ITE, Standard Operation, TM3, , TM3 disconnection
|
TM3 has been disconnected this morning and purged all HV water lines. I found the power plug for all turbo pump fans wasnt connected during
the last run. That maybe the one of the reason on that ITE TP3 failure. |

Saturday, May 06, 2017, 13:30, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 current limiting
|
Today the voltage was raised from 65kV to 65.7kV. After about 10min at this level TM3 started current limiting. TM3 was not sparking when this happened.
ISAC OPS turned it OFF and then tried to ramp it back ON, but could not do it due to the current limiting.
I turned OFF/ON the PS (locally) 20ming ago and and then tried to get it back from the Control Room, but around 4-5kV it started current limiting. |

Thursday, July 04, 2024, 01:20, Carla Babcock, ITE, Development, TM3, SiC#46, TM3 conditioning with protons
|
Initial Summary:
TM3 sparking behaviour in ITE has been very disruptive both with and without protons. Protons are at 60uA, target heater at 540A. Max voltage achieved
so far is 51kV, limited by time and a current limit on the BIAS supply. |
