Info on proposed steel shield experiments using the T-Gun at GTS
Previous Parameters
- Gun Voltage: 100 kV
- Gun Solenoid Current: 150 A. Experiments varied the current between 30 A and 150 A
- Anode Voltage: 1 kV (961 V). Experiments varied the anode bias voltage between 388 V and 961 V
- Beam Current: 100-500 uA
- Gun Vacuum Levels: Usually > 1e-9 A ion pump current at the gun
Proposed Parameters
- Gun Voltage: 90 kV (should be fine for experiment purposes)
- Gun Solenoid Current: 150 A
- Anode Voltage 1 kV
- Beam Current 500 uA or higher (to ensure sufficient measured intensity from recombining ions)
- Gun Vacuum Levels Higher pressure -> higher ion production rate -> higher number of recombining ions.
