CHARGED PARTICLE BEAM IRRADIATION SYSTEM

摘要

A charged particle beam irradiation system including: an accelerator configured to accelerate charged particles and emit a charged particle beam; a stand in which an irradiation section is disposed; a transport line which has an energy selection system configured to extract a charged particle beam having a second energy width smaller than a first energy width from a charged particle beam having the first energy width, emitted from the accelerator, and is configured to transport the charged particle beam from the accelerator to the irradiation section; and a building having an irradiation chamber and a separate room, wherein the accelerator is disposed in the irradiation chamber, the energy selection system of the transport line is disposed in the separate room, and the building has a partition wall which separates the irradiation chamber and the separate room and is configured to shield against radiation.

1. A charged particle beam irradiation system comprising:
an accelerator configured to accelerate charged particles and emit a charged particle beam; a stand in which an irradiation section configured to irradiate the charged particle beam to an irradiated body is disposed; a transport line which has an energy selection system configured to extract a charged particle beam having a second energy width smaller than a first energy width from a charged particle beam having the first energy width, emitted from the accelerator, and is configured to transport the charged particle beam from the accelerator to the irradiation section; and a building having an irradiation chamber in which the stand is disposed, and a separate room in which a portion of the transport line is disposed, wherein the accelerator is disposed in the irradiation chamber, the energy selection system of the transport line is disposed in the separate room, and the building has a partition wall which separates the irradiation chamber and the separate room and is configured to shield against radiation that is emitted from the energy selection system.
