An ion diode with an orificed anode and an external radial magnetic field created by a pair of concentric windings is described. It is distinguished by the absence of devices for preliminary plasma production. The diode is powered from a high-current nanosecond-pulse accelerator with a matching output autotransformer. The use of ballistic focusing in a converging ion beam makes it possible to reach an ion-current density of 600 A/cm 2 at an efficiency of ∼60%, relative to the energy stored in the accelerator's forming line, and at an anode potential of ∼350 kV for a half-height voltage-pulse duration of 50 ns.
