Abstract
An accelerator system which can be implemented in a small size at low manufacturing cost and which can nonetheless ensure a high utilization efficiency of the ion beam. The system includes an ion source for generating an ion beam, pre-accelerators for accelerating the ion beam generated by the ion source, an radioisotope producing unit for irradiating a target with the ion beam accelerated by the pre-accelerators for producing radioisotopes, a synchrotron into which the ion beam accelerated by the pre-accelerators is injected and from which the ion beam is ejected after acceleration, and a selector electromagnet for introducing the ion beam accelerated by the pre-accelerators into either the radioisotope producing unit or the synchrotron.
Claims4
An accelerator system, comprising:
- an ion source positioned in a pre-accelerator chamber shielding radiation for generating an ion beam;
- pre-accelerator positioned in said pre-accelerator chamber for accelerating the ion beam generated by said ion source;
- a radioisotope producing unit positioned in a radioisotope chamber shielding the radiation for irradiating a target with the ion beam accelerated by said pre-accelerator to produce a diagnositc radioisotope;
- a synchrotron positioned in a synchrotron chamber shielding the radiation, into which the ion beam accelerated by said pre-accelerator is injected and from which the ion beam is ejected after acceleration;
- and
- a selector electromagnet for introducing the ion beam accelerated by said pre-accelerator means into either said radioisotope producing unit or said synchrotron;
- a first shielding shutter positioned in a first beam passage communicating between said selector electromagnet and said radioisotope producing unit;
- a second shielding shutter positioned in a second beam passage communicating between said selector electromagnet and and said synchrotron;
- and
- an irradiation system positioned in an irradiation chamber shielding the radiation for irradiating an affected part of a cancer patient with the ion beam ejected from the synchrotron.
