  • Attempts to run at 1 mA:
  1. Ran for few seconds before a HV arc. QE dropped by a factor of 2.
  2. Ran again for 1.5 hours (with ion-precipitators on) before a HV arc. QE dropped by another factor of 2.
  • Down Monday - Wednesday to:
  1. Degas dump with NEGS at 25% on for ion pumps to take vacuum load.
  2. Replace ND filter from ND1 to ND3.
  3. Re-activate photocathode with 3 mm active area.
  4. Instrument wire scanner
  5. Install WiFi access station and enable JMenu on PC in GTS cave.
  6. Why is Dump/FC reading -20 nA?
  7. Hi-pot VIPGT06.
  8. SCAM VL frequency is not 60 Hz?
