摘要：
The purpose of the present invention is to provide a small particle beam radiation apparatus which has a rotational gantry that is equipped with an accelerator which is lightweight due to employing a superconducting air core coil. This particle beam radiation apparatus (59) includes a particle beam circular accelerator (51) that is supported by a rotational gantry (60), a beam transport system (54), and a radiation field forming device (56). The particle beam circular accelerator (51) includes: a pair of superconducting coils (3a, 3b) which are symmetrically arranged with respect to an acceleration trajectory surface (12) and a pair of pole tips (7a,7b) which are arranged inside the superconducting coils (3a, 3b), are symmetrically arranged with respect to the acceleration trajectory surface (12), and produce, from a magnetic field generated by the superconducting coils (3a, 3b), a magnetic field distribution that causes a charged particle beam (16) to move orbitally in an accelerating cavity (11). Each pole tip (7a,7b) has a thin portion (26) which is where the thickness between the inner surface (18) and outer surface (22) is smallest, the thin portion (26) being arranged such that at least half of the thin portion (26) is present on the outer periphery side of an intermediate line (29) which is located midway between a coil axis (17) and the outer peripheral edge of the pole tip (7a,7b).Le but de la présente invention est de fournir un petit appareil de rayonnement à faisceau de particules qui a un portique rotatif qui est équipé dun accélérateur et qui est léger en raison de lutilisation dune bobine à air supraconductrice. Cet appareil de rayonnement à faisceau de particules (59) comprend un accélérateur circulaire de faisceau de particules (51) qui est supporté par un portique rotatif (60), un système de transport de faisceau (54), et un dispositif de formation de champ de rayonnement (56). Laccélérateur circulaire à faisceau de particules (51) comprend : une p
