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 |

TM3 UCx#44 after operation electrical check at SHC . see attachment.
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. |

Work on TM3 source tray removal started at 10:40 am today.
The containment box has been removed, and disconnection of the optics tray is 90 complete.

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.
Notes and description of problems encountered during the installation: |

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 |

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. |

Monday, August 26, 2013, 18:22, Grant Minor, South Hot-Cell, Repair, TM3, , TM3 Rev 3 - all connetions made except steerers, IMG, and entrance window 8x
|
Today Chad finished making all connections to the new source tray, except for:
- steerers - broken wire, must be repaired at a later date
- IMG gauge - bracket required, old bracket thrown out with previous tray by accident, see ITA3301, must be installed at a later date |

Optics tray has been removed from module.
Waterblock jig installation has commenced. Of note, jig installation on TM3 has proven more dificult than the previous installation on TM2. Many
of the waterblock assemblies are skewed (not perpendicular to plane that they should be...perpendicular to). |

On Friday, June 22 the following work was carried out.
Further inspection of the source tray.
Testing of existing tray removal and installation tool...it works fine, there was
just a specific method for proper coupling to the target module. There was no documentation for this tool, so it took a little bit of insight with |

We have a ram installed on SHC pole which is 0.5 meter to module shielding block surface. the readings we got today during TM3 move:
at containment box center (highest reading): 3.14 msv/hr.
at bottom of shielding blocks: 960 usv/hr. |
