TM4 has seen significant coating of the main standoff insulators and various other components stemming from failure in UCx#43 target. See attached pictures showing coating on containment box, support frame, main standoff insulators, standoff insulators high voltage shield etc. Note tracking marks on main standoff insulators.

Meggered all HV components relative to HV common and HV common relative to ground. Nothing out of the ordinary, HV common to gnd was 700MOhms at 1kV. Seems whatever got onto the insulators is non-conductive, or is not as bad as it seems. |

Wednesday, January 25, 2023, 06:52, David Wang, ITE, Standard Operation, TM4, UCx#41, ITE primary and secondary vacuum vessel air to vacuum seals leak check.
|
ITE primary and secondary vacuum vessel air to vacuum seals leak check was done this week. One leak has been found on IG1S feed through to entrance module surface seal. It explains what we saw on ITE IG1S readings change(from low E-7 torr to 1Xe-6 torr) on December 22, 2022. This leak seal will be replaced soon.
2023-Jan -27. O-ring seal 229# was replaced on ITEIG1S feedthrough to entrance module surface sealing. Also o-ring seal 034# was replaced on the blank off cover beside the feed through to entrance module surface sealing. Since these o-rings are too close to each other. It is better to replace both of them to avoid misreading in leak check. |
