A new scheme of the cathode assembly of a high-current electron gun is presented. Initiation of explosive emission is performed with the help of sixty nine simultaneously operating spark gaps which electrodes and tube ceramic isolators are inserted into a disc explosive-emission cathode. The operability and high emissivity of the cathode assembly which exceeds by 1.5‒1.7 times the value inherent in traditional scheme of an electron gun with plasma anode and copper-braid explosive-emission cathode has been demonstrated.
