- Abstract
A new scheme of the cathode assembly of a high-current electron gun is presented. The initiation of explosive emission is carried out using of 69 parallel triggered spark gaps, the electrodes and tubular ceramic insulators of which are built into the disk explosive-emission cathode. The efficiency of the proposed scheme and the high emissivity of the cathode assembly, which is approximately 1.5–1.7 times higher than the emissivity that is characteristic for a traditional gun scheme with a plasma anode and a copper-braided explosive emission cathode, are demonstrated.
