    摘要： A dynamic magnetic field feed device feeds a magnetic field at predetermined timing to a predetermined region through which an ion beam having desired energy circulating in an acceleration space passes, and displaces a circular orbit of the ion beam having the desired energy. An extraction channel is arranged on an outer periphery of a magnetic pole. A position O1 where an ion introduction device introduces ions into the acceleration space is a position closer to the extraction channel relative to a center O2 of the magnetic pole. A region to which the dynamic magnetic field feed device feeds a magnetic field is a region closer to an opening of the extraction channel relative to the position O1 where ions are introduced, and the magnetic field to be fed is a magnetic field in a direction where the main magnetic field is strengthened.

    摘要： A lead shielding for a betatron in an X-ray generator is provided that includes at least four shielding parts of which two are semi-cylindrical and provided with recesses in the envelope surfaces thereof. The semi-cylindrical shielding parts are arranged in corresponding recesses of the remaining shielding parts by means of the envelope surfaces thereof, such that the recesses in the envelope surfaces form air channels between the semi-cylindrical shielding parts and the remaining shielding parts.

    摘要： A Betatron having a toroidal passageway disposed in a cyclical magnetic field with a main electron orbit circumnavigating the toroidal passageway. Within the toroidal passageway is a first electrode that is spaced apart from a second electrode. The combination of the first electrode and the second electrode define a central space having a first opening and a second opening. A cathode is disposed within the central space. This cathode has a first electron emitter aligned to inject electrons through the first opening and a second electron emitter aligned to inject electrons through the second opening. Electrons injected in a proper direction are accelerated in the main electron orbit. At a time of maximum electron acceleration, the electrons are deflected and impact a target that generates x-rays on impact.
