Abstract
An ion source for use in a radiation generator includes a sealed envelope containing an ionizable gas therein. The ion source also includes a RF antenna external to the sealed envelope, the RF antenna to transmit time-varying electromagnetic fields within the sealed envelope for producing ions from the ionizable gas. There is at least one extractor within the sealed envelope having a potential such that the ions are attracted toward the at least one extractor.
