【 摘 要 】

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.
