Abstract
An ion source includes a chamber. The ion source further includes a first hollow cathode having a first hollow cathode cavity and a first plasma exit orifice and a second hollow cathode having a second hollow cathode cavity and a second plasma exit orifice. The first and second hollow cathodes are disposed adjacently in the chamber. The ion source further includes a first ion accelerator between and in communication with the first plasma exit orifice and the chamber. The first ion accelerator forms a first ion acceleration cavity. The ion source further includes a second ion accelerator between and in communication with the second plasma orifice and the chamber. The second ion accelerator forms a second ion acceleration cavity. The first hollow cathode and the second hollow cathode are configured to alternatively function as electrode and counter-electrode to generate a plasma. Each of the first ion acceleration cavity and the second ion acceleration cavity are sufficient to enable the extraction and acceleration of ions.
