The problems in the formation of electron beams of microsecond duration, electron energy 500-600 keV, and current density up to 20-30 A/cm2 with a rectangular cross-section of area 0.1-1 m2 in high current electron accelerators with explosive emission cathodes are considered. The designs of vacuum diodes capable of producing such beams to be used in high-power lasers and for the ionization of gases in large volumes are also presented. The use of electron accelerators with explosive emission cathodes enable one to produce electron beams with parameters ranging over wide limits beyond the reach of electron accelerators of other types.
