[Tgun] [Revised Logentry] Plan 8-2-19

Logentry Text:

Status:

HV power supply has no remote control
Floating ground for Bias supply not complete
possible faulty connection on the anode (odd type of BNC)

Plan:

Fay to contact Spellman to try and resolve the issue
Riad: test the supply at low kV in local mode with the HV cable removed. Make safety aware of this test.
Riad: pursue short term solution of longer HV cable and moving supply upstairs (assuming local works)
Mamun: set up heat tape around the gun vacuum chamber and prepare (but not start yet) a 150kV bake.
Mark: prepare the grid bias supply with modified connector for processing purposes. This way we can have the cathode hot during processing so as to not poison it.
