Characteristics and behavior of the electron beam of the МИН-1 accelerator in air

摘要

The electron-beam characteristics of the MИH- 1 accelerator have been measured. At the output of the accelerating tube, the current-pulse amplitude is ～1 kA, duration ～10ns, and maximal electron energy ～600 keV. As the beam passes through the air, its diameter increases linearly with the distance varying from 2 cm at the tube window to ～45 cm at a distance of 1 m from it, which agrees with the calculations performed.
