Characteristics of an “orbitron” ion source with a two-wire anode
- 15 Downloads
An orbitron-type ion source is considered, with a cylindrical cathode and two wire anodes, operating at hydrogen pressures of 0.07–0.5 Pa with a firing voltage of 1–5 kV and mean discharge current of several mA. In pulsed high-current operation, a peak current of 25 A can be achieved with 2–3-μsec pulses. The ion current is extracted through two longitudinal slits in the cathode and reaches 30% of the discharge current. The source performance is analyzed as a function of the gas pressure and geometrical parameters.
