Title: ELECTRON BEAM IRRADIATION DEVICE AND METHOD FOR USING SAME
Abstract:
An electron beam irradiation device (1) provided with a vacuum chamber (2) having an electron beam generator (20) disposed therein, a vacuum nozzle (3) that is in communication with and is connected to the vacuum chamber (2), and an emission window (5), provided in the vacuum nozzle (3), that transmits an electron beam (E) from the electron beam generator (20) and emits the same to the outside. A refrigerant path for guiding refrigerant is formed in the vacuum nozzle (3). The electron beam irradiation device (1) is provided with a refrigerant temperature adjuster (7) for adjusting the temperature of the refrigerant guided through the refrigerant path such that the relative humidity around the nitrate (N) deposited on the surface of the vacuum nozzle (3) suppresses the deliquescence of the nitrate (N).
