ABSTRACT:
In an electron beam-generating system including an electron-emitting cathode, a beam focusing electrode, and an anode electrode for accelerating the emitted electrons, the magnetic fields for deflecting the beam to material to be heated and for periodically deflecting the focal spot of the beam on the material are produced by a heavy current conductor, that is, a conductor carrying a high current, arranged in proximity to the curved path of the deflected electron beam and extending perpendicular to the plane of deflection of the electron beam. The anode electrode may be formed with an opening for the passage of the electron beam, and the heavy current conductor is arranged in the proximity of the opening and parallel to the latter. The heavy current conductor may be designed as an edge of a slot-shaped opening, and may comprise a plurality of individual conductors.
