Abstract

The research results of the perveance of the diode with a blade explosive emission cathode under different diode gap-to-cathode radius ratio are presented. The blade cathode is made from the coiled copper band. The applied voltage pulse duration is 450 ns (at the level of 0.1-0.9) at a peak accelerating voltage of 400 kV. A distinguishing feature of an electron beam generation in the experiments carried out is a rather high duration of the accelerating voltage front, which is over 0.1 μs. On the basis of the experimental data, we suggested an analytical model for variation of the diode perveance allowing for the effect of the edge effects on the blade cathode during the generation of an electron beam. The model describes adequately the behavior of the diode perveance under changes of the ratio d_AK/r = 0.7-1.4 and of the cathode material.
