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 |

|
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. |

Tuesday, July 09, 2024, 16:14, Carla Babcock, ITE, Repair, , , Attempts to reduce ITE:EL trips from HV sparks 8x
|
ITE:EL has been tripping off due to HV sparks. Usually this also trips ITE:Q1/2. These are sitting in side-by-side racks.
The working theory is that HV sparks are returning to ground through the EL and quads, tripping them off. Possibly this is the result of a changed
low impedance ground path. How this change happened could be either something we did during shutdown or the changes we made in TM3, no clear evidence yet. |
