 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
