Thursday, September 28, 2017

Cooling water not yet connected to TM.

High leakage current still observed. 200 uA at 22 kV. Did not go past 25 kV. 


Friday, September 29, 2017, 14:05: Started heater ramping to 580 / 200 A at 1 A/min

Friday, September 29, 2017, 14:09: BIAS / EZL / EE at 20 / 10 / 1.5 kV. BIAS current at 90 uA


Monday, October 02, 2017, 10:29: Accidentally set BIAS current limit to 0 A (step size too large) at 28 kV. This also caused the TGHT to got to 0 A. Recovered to 580 A in 10 - 15 s.

Monday, October 02, 2017, 12:07: Ramping down heaters at 2 A / min
