At the lower right is the plate supply routing. Note the use of a 9-pin Molex connector (only the center pin is used). 5KV meter lead wire was used here, and was also placed inside plastic tubing for extra insulation.  The plate supply is also routed to the HV metering resistors towards the top, away from other cabling. Also visible here is the routing of the coolant lines to the tube.

Note the disconnects for the other cavity electrical connections. 3 different connector types are used to prevent accidental misconnections. These disconnects are used when the cavity must be serviced (changing the tube).
