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 |

NEW HV cable for BIAS installed earlier this week.
Wednesday, June 28, 2017, 16:42: BIAS at 20 kV
Wednesday, June 28, 2017, 16:46: BIAS at 30 kV, EZL at 15 kV
Wednesday, June 28, 2017, 17:00: BIAS at 35 kV, EZL at 17.5 kV
The voltage response on TBHT and TGHT changed as the target was heated up. This was later determined to be due to target shorting to heat shield and the grounding of the power supplies being achieved at the HV pedestal in the target hall and not in the HV enclosure as is done online. When this was changed, the target operated normally again. |
