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.

摘要： The radiotherapy apparatus in the present invention includes a bed, a radiation irradiating head, head swing mechanisms, a precise inspection unit and a control unit. The bed carries a subject. The radiation irradiating head irradiates a treatment radiation to a treatment field of the subject. The head swing mechanisms, which are coupled to the radiation irradiating head, swings the head of the radiation irradiating head so that the treatment radiation emitted from the radiation irradiating head pursues the motion of the treatment field. The precise inspection unit obtains a diagnosis image containing the treatment field. The control unit controls the positions of the head swing mechanisms so that an irradiation field of the radiation irradiating head pursues the treatment field, based on the diagnosis image, the position of the radiation irradiating head and the state of the swung head. Then, the control unit controls the radiation irradiating head so that the treatment radiation is irradiated from the radiation irradiating head, after the positional control of the head swing mechanisms.

摘要： In an acceleration tube conditioning apparatus for performing a conditioning process on an acceleration tube when a high frequency power signal to be supplied to an acceleration tube is generated by a high frequency power supply, a power value collecting section collects a traveling wave power value and a reflection wave power value from a sensor which monitors the traveling wave power signal and the reflection wave power signal. A high frequency calculating section calculates a resonance frequency of the acceleration tube based on the traveling wave power value and the reflection wave power value. A high frequency adjusting section determines a high frequency value based on one of the traveling wave power value and the reflection wave power value as a selection power value, and a high frequency power supply control unit controls the high frequency power supply based on the high frequency value. The high frequency value indicates a constant value when the selection power value is smaller than a predetermined value, and indicates the calculated resonance frequency when the selection power value is larger than the predetermined value.
