|
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. |

Friday, August 09, 2024, 18:20, David Wang, ITW, Standard Operation, TM3, TiC#8, TM3 has been moved from SHC to ITW.

| With TiC # 8 installed, TM3 has been moved from SHc to ITW. The move is smooth. |
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.

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. |

|
Tuesday, May 14, 2024, 10:26 :
Ramping up bias/EE/EL on ITE - will see if the HV cage in the pit can hold 60kV or not.
At around 50kV the bias read current starts to get jumpy. Doesn't look like its an issue for the voltage, but definitely instability increases. |

Thursday, September 08, 2016, 16:28, David Wang, Conditioning Station, Repair, TM3, , TM3 blue insulators have been replaced.
|
All TM3 blue insulators except Gas,EL, and 60 KV common on top of the module have been replaced with new designed insulators. The new blue insulator
for gas line need to be modified to fit for the bent on the gas line. EL, and 60KV common blue insulators were replaced during last time
TM3 refurbishment so they are relative new, and not replaced this time. All seals related to the blue insulators are changed to new seals. The o- |

Friday, March 07, 2014, 12:45, David Wang, ITE, Standard Operation, TM3, , TM3 and ITE air to vacuum leak check and TM3 water lines helium test.
|
With TM3 located in ITE, All air to vacuum seals on ITE primary and secondary vacuum vessel have been leak checked with leak detector hooked
directly on the TM3 service cap.The base LR :00xE-9atm.cc/sec. The ITE IG1 was 1.6xE-6 torr which was good. No leak has been found during the checking.Also,
the TM3 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITE and |

Carla: Looks like the short on the cathode observed while trying to operate the FEBIAD in cathode-bias mode is still there. Will do investigations
in the hot cell during disassembly. |

Monday, October 20, 2014, 09:13, David Wang, Conditioning Station, Development, TM3, , TM3 TP2 failed
|
TM3 TP2 stopped working this morning at 4:00 AM. I tried to start it but failed. On normal start mode , It could not pass 6K RPM. On soft start mode
, the pump cant pass 17KRPM. Talked with Anders, We are not going to replace this pump since we are not going to run this module for a while. I will stopped
all vacumm pumps on CS and TM3 this morning. |

The source tray has sucessfully been removed from TM3.
I will put a report in the TM3 rev 3 docushare directory as there were some items of note during this procedure. |

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. |

After a great struggle with the water block jigs, the TM3 source tray was finally advanced fully into the service tray and all water blocks were connected
and torqued to spec in the hot cell by Chad Fisher.

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:

Friday, August 23, 2013, 18:32, Grant Minor, South Hot-Cell, Repair, TM3, , TM3 Rev 3 - steerer wire broken from connector on module side
|
While continuing on the TM3 Rev 3 source tray installation, Chad noticed today that one of the steerer wires is broken and has come out of the thermocouple-style
connecter block (see attached photos).
From drawing ITA2826 (Rev D02 attached) it is likely that this is for either the "upper" or "right side" steerer plate. |
