FGT Ramping Results
HV was ramped successfully for all 14 quarter sections. Here are the details:
- Mapping
- HV ramping: Manual ramping 1000V and 2000V at 60V/s and then slowly to 3000V and 3600V at 10V/s
- Leave HV at 3600V for about 10min.
- Beam conditions: Single beam (24GeV, low current at the level of 1.6-1.7 10^11, Injection mode Blue beam)
- Results: No problem with any ramp / Current consistent with overall resistivity of voltage divider
