Abstract

PURPOSE:To easily perform surface treatment of the inner and outer faces of a cylindrical material to be irradiated by utilizing pulse electron beams and forming an anode, a cathode and the material to be irradiated into a cylindrical shape and coaxially arranging them. CONSTITUTION:An anode 5, a cathode 6 and the material 10 to be irradiated are formed into a cylindrical shape and these are coaxially arranged. The material 10 to be irradiated is directly fitted to the inner face of the anode or utilized as the anode 5. Pulse voltage is impressed between the cathode 6 and the anode 5. The inner face of the material 10 is irradiated with the pulse electron beams 8 generated from the cathode 6. Thereby necessary surface treatment is performed on the inner face of the material 10 to be irradiated. Further in the case of treating the outer face of the material 10 to be irradiated, the cathode 6 is arranged to the outside of the anode 5 and the material 10 to be irradiated is fitted to the surface of the anode 5 or utilized as the anode 5. Thereby surface treatment of the inner and outer faces of the cylindrical material 10 to be irradiated is easily performed.
