|
SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.
Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray. I will again warn that the source trays historically have a life expectancy, and that TM4 continues to show visual signs that the current source tray is rapidly approaching the end of its useful life!
I understand that one of this years goals is to retrofit TM3; however I fear TM4(and possibly TM1) may fail before this can be released. With the current absence of backup source trays and modules I fear we leave the ISAC program in a very vulnerable position.

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. |

|
TM4 has been connected at CS. CS HV cover is installed.I made a pair of new cooling lines for TM window cooling at CS. The TM4 containment box window cooling line is connected to the HVC spare circuit now. I checked water flow visually, and it is good. The TM4 is ready for conditioning.See attachment for window cooling modification.
