An induction accelerator system has been successfully operated to postaccelerate an intense pulsed ion beam that is highly space-charge and current neutralized. An annular ion beam (energy 90 keV, current 5.7 kA, pulse width 750 nsec) extracted from an applied-Bᵣ magnetically insulated diode is injected into the induction accelerator, where a short pulse (210 kV, 50 nsec) is applied. Measurements of beam energy by a Thomson-parabola spectrometer before and after the postacceleration have confirmed the increase in beam energy of H⁺ up to {~}240 keV after being postaccelerated.
