摘要： A particle therapy system capable of measuring energy of a charged particle beam even during irradiation of the charged particle beam is provided. A beam delivery (irradiation) system comprises a block collimator constituted by a pair of collimator members, and an energy detector mounted to one of the collimator members to be disposed on the upstream side thereof. When the pair of collimator members are moved in directions away from each other, a beam passage is formed between them. The energy detector constitutes an energy measuring device together with a signal processing unit. A part of the ion beam having reached the interior of the irradiation nozzle is irradiated to a patient through the beam passage. When a part of the remaining ion beam enters the energy detector, electric charges generate in the energy detector. The signal processing unit determines energy of the ion beam based on a position within the energy detector at which electric charges have generated in maximum amount.

摘要： A circular accelerator is arranged to circulate a charged particle beam through a bending function provided by a bending magnet, set a tune of the charged particle beam being circulated as it is betatron-oscillated to a predetermined value through the effect of a quadrupole magnetic field, resonate the charged particle beam being circulated at the tune set to the predetermined value in a manner to increase an amplitude of the betatron oscillations over the stability limit of resonance, thereby extracting the charged particle beam. The circular accelerator includes a bending magnet formed to generate a quadrupole magnetic field component for horizontally focusing the charged particle beam being circulated and vertically defocusing the beam and another bending magnet formed to generate a quadrupole magnetic field component for horizontally defocusing the charged particle beam being circulated and vertically focusing the beam. The accelerator is reduced in size, easily operated, and enables to keep the location of the beam extraction and the diameter of the beam constant and output an excellent charged particle beam.

摘要： The present invention provides apparatus for acceleration of a charged particle beam which includes energy means for altering the energy of a circulating beam circulating in the apparatus and means for extracting output beams from the apparatus. Control means are arranged to be operable to alter the energy of the circulating beam using the energy means so as to be able to extract output beams of at least two energies from the apparatus using the means for extracting. Thus there is provided an accelerator, and an extraction method therefor, which is capable of extracting a small diameter beam having a varying energy level. This facilitates improved medical irradiation treatment using the beam.
