The distribution of magnetic-field induction in the accelerating gap of an ion diode with external magnetic insulation is studied. The absence of a device for preliminary plasma production is a distinguishing feature of this diode. It is shown that a certain configuration of the magnetic field near the anode surface allows an increase in the ion-diode efficiency to 70%, and the ion-current density at the diode focus then reaches 350 A/cm~2.
