  1622   Thursday, September 21, 2017, 16:26 Anders MjosSouth Hot-CellStandard OperationTM2 Inspection of Source Tray

Chad and Anders inspected the Source Tray today using the camera in the hot cell. A dark spot was observed on one of the four insulators separating the Extraction Electrode from the Ground Electrode. This could potentially influence the high leakage current. Some discolored areas were also observed in the Service Tray, but these was present when the module was built. See attachment for details.

Two side panels on TM2 service cap were removed for TM2 service cap inside inspection. A piece of cable tie was found inside cap closing to service tray entrance area. All blue nylon insulators are inspected. They look good. The broken cable tie is moved out of service cap.

 Panels are installed back after the inspection.

Yesterday Aaron, Isaac and Anders inspected the EZL connection from the service chase to the optics tray using the goose neck camera in SHC. No issues or shorts could be identified. Containment box was not removed.

Today David and Anders opened up two panels on the service cap and inspected the EZL connection. No issues or shorts could be identified. Photos available on DocuShare.

Next step will likely be to remove the containment box and inspect the optics tray.

The containment box was removed yesterday. One of the main insulators on the source tray had cracked at the rear close to the bolt to the source tray mounting plate (see photos using link above)

Troubleshooting continued this morning with disconnection of the optics tray from the module. The banana plug copper tube connection was removed form the optics tray side. With the connection removed, the measurement showed open line on top of the module indicating that the problem is on the optics tray
