 Friday, April 6, 2018, afternoon: Due to inconsistencies on EPICS, Carla and I Change the Anode power supply to local in order to monitor the leakage current with a multimeter.

Monday, April 9, 2018, afternoon: TBHT@350A and TGHT@550A 

PS went current limited at AnodeBias=300V and show 3A on the PS Screen, the multimeter read the same.

Ramp down to 0 V 0A on PS. PS shows 0.01V

PS goes to limited current even at 2V.

Tuesday, April 10, 2018, 09:10: Problem persists even at lower TBHG (330A). 

The output cable was removed and the power power supply seemed to behave better. This could mean that there is a short inside the unit, in the past the anode cable had melted into the cup.

Planning to ramp down the TBHT and see if the behaviour remains. If it does, I would ask to remove the unit for inspection.

Tuesday, April 10, 2018, 09:32 : Ramping down TBHTH to 250A

Tuesday, April 10, 2018, 13:07 : Same behaviour. Cooling procedure started to see if the issue is still present, anf if it does remove unit for inspection

Tuesday, November 13, 2018, 16:44: The anode drain current has increased 17mA since 11:23 am, however FC0 is still decreasing. I will keep monitoring to see if the behaviour of the anode drain current continues once FC0 has stabilized. If the anode drain current keeps increasing maybe we will observe the same failure from the previous FEBIAD.

FM

Wednesday, November 14, 2018, 11:02 FC0 is stable but the anode drain current is still increasing and now is at 85 mA. It started at ~52mA. From the strip tool it seems to be a 2-hour period where the anode drain current is stable.
