Features of pulsed electron beam propagation with nanosecond duration in the air under the low (reduced) pressure

Abstract

This paper presents the research of pulsed electron beam propagation with nanosecond duration in the air under the low pressure (3-8 Torr) with the help of a calorimeter with a vacuum cutoff and a Faraday cup. Investigations have been conducted with the laboratory setup, including the TEU-500 electron accelerator and a drift tube. The major parameters of the accelerator are as follows: 450-500 keV electron energy; 9-12 KA ejected electron current; 60 ns half-amplitude pulse duration; 5 pps pulse repetition rate; and 250 J pulse energy.
