Abstract
An ion source for use in a radiation generator includes an active cathode configured to emit electrons on a trajectory away from the active cathode, at least some of the electrons as they travel interacting with an ionizable gas to produce ions. In addition, there is at least one extractor downstream of the active cathode having a potential such that the ions are attracted toward the at least one extractor.
