The development of the permanent magnet system for the ion diode isolation

Abstract

The paper demonstrates the possibility of using the field of permanent magnets for the magnetic isolation of an ion diode and for the ion beam formation. To form a radial magnetic field of a given geometry, ring magnets of complex (special) shape were developed on the base of cylindrical permanent magnets. We also elaborated the design of the anode, magnet frames, and the cathode system of the ion diode. Investigations of the magnetic field parameters were carried out; and experimental data on the accelerating voltage and ion current density were obtained.
