Summary:Title screen
An electron source with a plasma emitter based on an arcdischarge system with six cathodes anda common cylindrical hollow anode is described. Upon synchronous initiation of vacuumarc discharges, thespace of the hollow anode is filled by dense lowtemperature plasma, the emission boundary of which is stabilized by a finestructure metal grid with a 150cm2 area. The arccurrent amplitude for each cathodeamounts to 100–300 A. Under the action of a constant accelerating voltage applied between the plasma emitter and grounded accelerating electrode combined with the drift tube, electrons are extracted from plasmaand accelerated. At a working pressure of 0.04 Pa, an electron beam with a maximum current amplitude of1 kA has been obtained at an initial accelerating voltage of 80 kV and pulse duration (FWHM) of 100 µs,which has been transported in a longitudinal magnetic field of 0.035 T over a distance of 80 cm.
