VUV Radiation spectra of erosion plasma of a jet of high-current diaphragm discharge in vacuum

Abstract

An experimental investigation is made of the effect of breaking of current in a vacuum-arc discharge as a result of superposition of a pulsed axisymmetric magnetic field with longitudinal and transverse components. A study is made of the dependences of the probability of breaking of current on the current magnitude, the pulse amplitude of the magnetic field, and the value of emf of the electric circuit in the current range of 100 to 600 A. The main factors affecting the probability of breaking of current are analyzed.
