Abstract
The tightly pinched electron beam of a pulsed electron accelerator is used to generate an intense beam of ions. A foil anode and vacuum drift tube are used. The space-charge field of the pinched beam in the tube accelerates ions from the foil anode. Ion currents of 10 kA at a density of 5 kA/cm2 with pulse length of 50 nsec are obtained using a 5 kJ, 450 kV, 3Ω diode.
