Gas release of the dielectric coating of an anode and its effect on the characteristics of an ion diode with electron flux insulation by a radial magnetic field

Abstract

Generation of an ion beam by an ion diode is accompanied by the release of gas from the surface of the dielectric coating of the anode. The magnitude of the pulse pressure of gas in the vacuum chamber depends on the type of the dielectric used and can reach 6 × 10^–4–2 × 10^–3 mm Hg. The magnitude of the limit vacuum chamber pressure at which ion beam parameters remain constant has been found. Characteristics of the ion beam current in the vacuum chamber pressure range of 2 × 10^–4–1.3 × 10^–3 mm Hg are presented.
