An intense pulsed barium ion source

A magnetically insulated diode has been used to produce 30 A/cm2, 250 keV, Ba+ ion pulses for 170–200 nsec, using BaF2 as the ion source material. Other operating conditions yield pulse of Ba+and F+ ions at 300 keV and Ba+2 ions at 600 keV. The beam is diagnosed with time-of-flight analysis, Secondary Ion Mass Spectroscopy, and Rutherford backscattering of 2.3 MeV helium ions.
