A System for Extracting an Electron Beam into the Atmosphere Based on a Plasma Emitter Gun

Abstract

The main characteristics and schematic of a device for extracting a focused electron beam into the atmosphere are described for a gun with a plasma emitter. It is shown that guns with a plasma emitter can be used to produce zinc oxide powders with particle sizes of around 100 nm in the atmosphere. Results are presented from the nonvacuum electron beam deposition of coatings based on carbides of refractory metals. The possibility of welding aluminum and copper parts with an electron beam at atmospheric pressure is demonstrated.
