Abstract: An ion generating device including a time-varying electromagnetic power source; and a multi-antenna ion source including a plurality of live antennas electrically coupled to the power source; and a grounded antenna. A neutron generator, including a time-varying electromagnetic power source; a hermetically-sealed tube; a multi-antenna ion source within tube, the multi-antenna ion source including a plurality of live antennas electrically coupled to the time-varying electromagnetic power source; and at most one grounded antenna; an extractor adjacent to an aperture of the multi-antenna ion source; at least one magnet generating a magnetic field substantially parallel to a longitudinal axis of the multi-antenna ion source; a target within the hermetically-sealed tube; and a plurality of electrodes for accelerating and/or decelerating ions toward the target, where the power source operates at a frequency corresponding to a cyclotron frequency defined by a value of the magnetic field within the multi-antenna ion source.

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.

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.
