Wiring which was changed to run the mass marker tests has been reverted:
- anode bias cable connected to "B"
- tube negative attached to HV common through "B" to "F" connection

Monday, December 19, 2022, 12:06 : Tomislav changed the polarity of the anode power supply last week and everything has been closed up again. The anode wire was switched to feedthru J and the short there removed. Forgot to put the short on the tube before closing the top but it should be ok for these tests since it has the resistor still installed to keep it at some potential. Pumping out gas lines.
Monday, December 19, 2022, 12:46 : Anode voltage ramped to 500V no problems. BIAS\EE\EL at 30kV\-1kV\13kV. Starting heaters ramping to TGHT=600A TBHT=290A.
Tuesday, December 20, 2022, 08:23 : Cancelled heater ramp at 500A yesterday, resuming now.
