Perturbation of Reflective Discharge Plasma with a Hollow Cathode upon the Emission of Plasma Electrons

Abstract

Perturbation of a reflective discharge plasma with a hollow cathode upon the emission of plasma electrons through a small channel is studied experimentally. The energy spectrum of emitted electrons expands as the external accelerating electric field grows. This could be due to the emergence of an axial electric field in the discharge plasma of the inter-cathode space.
