Abstract
To study parameters of the diode electron gun with the current 80 - 100 kA (current density equals 1000 A/cm2), voltage 0,5 MeV, and pulse length 40 - 80 ns varied cathode materials was undertaken. Vacuum diode cathodes made of stainless steel, carbonic composite material and isotropic pyrographite are active in well-known explosion-emission regime. The cathode made of high-density pyrographite is active during all pulse-time in self-emission regime due to microspaces cooling with material anisotropic thermal and electrical conductivity.
