    Electron beam guns Paton-300

    Electron beam (EB) units are fitted with axial EB guns Paton-300 of 300 kW nominal power developed at the E.O. Paton Electric Welding Institute of the NAS of Ukraine.
    EB guns Paton 300 are electron beam heaters of axial type with tungsten cathode. Each gun is fitted with individual pumping down system which allows stabilization of EB gun operation under the conditions of intensive evolution of gases during ingot melting from initial charge materials.
