Abstract :
Summary form only given, as follows. The pulsed compact electron source with plasma cathode is considered in the report. The source consists of high voltage pulsed Marx generator and vacuum diode with plasma cathode on the basis of explosive electron emission. The plasma emitter on the basis of vacuum discharge forming on the surface of the nanotubes of cathode is used in this electron source. The electron source has next main parameters: accelerating voltage 100-150 kV, beam current 5-200 A, pulse duration 100-400 nsec. The experimental data for forming of cathode plasma: time and energy characteristics are discussed. The comparison of forming cathode plasma for carbon fibers and carbon nanotubes is experimental results with computer simulation is presented. The given. The physical model for explanation of forming stable cathode plasma is suggested.
