The variation law of the state of the electron diode and the output electron beam under the condition of burst pulse were studied. The equations of the parameters of the strong current electronic diode with the cathode plasma expansion effect were established. The model of the cathode plasma columnar expansion was proposed. The capability and beam quality of pulsed multi-pulsed high-current electron beam output by burst multi-pulse electronic diode were experimentally studied. The pulse output of the diode was obtained with a velvet cathode emitter and a cathode plasma with an expansion velocity less than 1 cm / μs Changes in network and electron beam emission and brightness.
