Latest revision as of 10:52, 9 September 2019

Update:
- Kr processing attempted - not really successful.
- 2 days under vacuum at 120kV, but with radiation increasing.
- Spare cathode is dead

Talking Points:
- Equipment damage during HV processing: Radiation gamma probe (again), Cathode Solenoid LCW flowmeter chassis (again)
- Magnetizing solenoid PS may be used in LERF for a while for isotopes.

Suggested Actions:
- Open up the gun - look for damage (take care with cathode). Look for anything around the screws for the cathode electrode
- Install the glassman supply as an alternative HVPS source (GTS 550 kV Glassman supply)
- One final change to the grounding of the Spellman, where HVPS chassis is grounded in the vault
