ABSTRACT:
An electron-beam heating apparatus in which an electron-beam of a stable intensity can be obtained. The apparatus is provided with a heating unit having two electrodes comprising a cathode and an anode. A heating of a material is performed by using an electron-beam generated by glow discharge generated in a space between the two electrodes. The apparatus is provided with an electric power source and a current control unit. The electric power source supplies an electric current to the electrodes so as to generate the glow discharge in a space between the two electrodes. The current control unit controls the current flowing to the cathode so as to be constant to obtain a constant glow discharge formed in a space between the two electrodes. A constant electron-beam is obtained by the glow discharge.
