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, June 17, 2024, 17:24, Carla Babcock, ITE, Development, TM3, UCx#44, Status of gas system prototype in ITE
|
A new gas system for FEBIAD operation was installed in ITE to enable us to use a calibrated leak which is attached to the target heat shield. This will
allow us to control the quantity and purity of the gas going into the system, and to switch quickly between gasese and pressures.
The schematic of the system is attached. The use of the ballast container is likely not needed - it was originally included in case we want to |

Monday, June 24, 2024, 14:37, Carla Babcock, South Hot-Cell, Development, TM3, UCx#44, Inspection of TM3 and UCx#44 after no-protons run
|
TM3 and UCx#44 ran in ITE but issues with the cyclotron prevented proton beam delivery. Nonetheless, the target was heated and provided stable beam to
TITAN as well as for tuning and some tests.
Results of inspection of TM3 module after run: |

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. |

|
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. |

Sunday, August 11, 2024, 11:25, Carla Babcock, South Hot-Cell, Repair, TM3, TiC#8, short on multipin wires to TBHT discovered
|
With the new TiC#8 target installed on TM3, there was a ~7kOhm connection between TGHT/TBHT (A/B/C/D) and HV common. The standard electrical check on
the module showed standard values, so it was assumed the problem was inside the target.
Started removing bolts/water connections one by one to see if any of them had an effect on the measurement. Found that disconnecting the multipin |
