摘要： An electron beam emitted from an electron gun enters into an accelerator 8 through a magnetic lens and is accelerated by a large number of accelerating tube discs within the accelerator, resonance cavities formed thereby and a magnetic field supplied from the outside. Then, it is focused by a focusing magnet and enters into an energy analyzer and scanned by a beam scanner, and is irradiated as a beam onto a sterilization goods item. On the outside of the accelerator there is disposed a cooling jacket for making uniform the thermal expansions of the resonance cavities due to thermal load. Also, by providing frequency adjusting means for adjusting the frequency of an accelerating microwave input through an input coupler and also by the cooling jacket having its thickness gradually increased from the inlet toward the outlet so as to make the thermal expansions of the resonance cavities zero, it becomes possible to make the amount of variation in the acceleration phase zero to thereby enable provision of an accelerator apparatus with large output and high energy density. Furthermore, in the energy analyzer, a particle energy necessary for sterilization is selected by bending magnet energy means and slit and irradiated, with the result that an effective electronic sterilizer apparatus can be realized.
