LONG LOW-ENERGY ELECTRON-BEAM IRRADIATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a long low-energy electron-beam irradiating device capable of increasing the width of irradiation, of improving maintainability and of equalizing an overheat characteristic. SOLUTION: This long low-energy electron-beam irradiating device is provided with: an elongated electron-beam generation part; a first electron-beam fixing base made of an insulating material and fixed to a flange part of a vacuum vessel at one end of the electron-beam generation part; a second electron-beam fixing base installed on the inside surface of the outer shell of the vacuum vessel through plural casters at the other end of the electron-beam generation part. The irradiating device is so structured that the electron-beam generation part is supported at both ends by the first electron beam fixing base and the second electron-beam fixing base.
