Accelerator and particle therapy system including thereof

Abstract

An acceleration radiofrequency acceleration system capable of frequency modulation and feeding an acceleration radiofrequency wave for accelerating a beam, a radiofrequency kicker 70 feeding an extraction radiofrequency wave different in frequency, from the acceleration radiofrequency wave for extracting a beam, a peeler magnetic field region 44 and a regenerator magnetic field region 45 for forming a disturbance magnetic field region including a high-order magnetic field that includes a magnetic field component having a number of poles of two poles or more and that includes at least a quadrupole magnetic field component, a shim of a magnetic material, and a septum magnet 43, 43A, 43B having an inner peripheral side septum coil conductor 5, an outer peripheral side septum coil conductor 6, a coil conductor connecting portion 7, and a coil lead-out portion 8 are provided.
