A gas-discharge electron gun relates to electronics and deal with development of gas-discharge electron guns of process purposes for powerful electron-beam installations. The gas-discharge electron gun comprises a sealed metal body housing a high-voltage input with insulators, a cathode assembly comprising cooled massive metallic blocks with changeable cathodes and cathode insulator, an anode and an anode insulator, a working gas ventilation system and focusing electrodes, whereon a wave guide with focusing and beam deflecting coils are positioned. is the fact that the electron-anode assembly provides multi-beam heating, the high-voltage insulators are made of fluoroflogopite stone casting. The invention provides substantially decrease cost of manufacturing powerful gas-discharge guns for s. |
