|
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: |

Tuesday, June 25, 2024, 12:49, Frank Song, ITE, Standard Operation, TM3, SiC#46, Module Connection
|
| TM3 with new target SiC#46 was connected in ITE. |

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, August 06, 2024, 09:16, Frank Song, ITE, Standard Operation, TM3, SiC#46, module disconnection
|
| TM3 with spent target SiC#46 was disconnected in ITE and ready to move to TCS soon. |
|
Thursday, August 08, 2024, 11:41, David Wang, South Hot-Cell, Standard Operation, TM3, SiC #46, Tm3 was moved from ITE to TCS this Tuesaday, then to SHC this morning.
|
| Tm3 was moved from ITE to TCS this Tuesday, then to SHC this morning. Both moves are successful. |

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. |

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 |
