330			_aPlasma cathodes are used in large-cross-section electron beam sources. The cathode plasma is created by a low-pressure arc discharge with a hollow anode. The physical processes in the discharge anode region associated with electron emission from the plasma and the formation of a stable plasma boundary as well as the methods used for reaching a more uniform electron current density distribution are discussed. The electron source designs allowing one to produce electron beams with currents of 10-103 A, durations of 10-5–10-3s, current densities of 0.1-1.0 A/cm2, and cross sections of ~104cm2 are described.
