An Intense Pulsed Barium Ion Source

Abstract
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+2ions at 600 keV. The beam is diagnosed with time-of-flight analysis, Secondary Ion Mass Spectioscopy, and Rutherford backscattering of 2.3 MeV helium ions.
