Self-pressed radiating theta discharge with trapped magnetic flux

Abstract

Numerical simulation of a radiating theta discharge pressed to the inner wall of a cylindrical dielectric chamber under the pressure of a trapped longitudinal magnetic field has been carried out in a high-pressure gas. The longitudinal magnetic field is created by a solenoid, which acts as inductive energy storage; an electro-explosive current breaker is used as an opening switch for this energy storage. It is shown that discharges of this type allow radial converging radiation fluxes of different spectral structures to be formed and the luminance temperature on the axis to vary in the range of several electronvolts.
