| 内容記述 | A superconducting rotating-gantry for carbon radiotherapy was developed. This isocentric rotating gantry can transport carbon ions with the maximum energy of 430 MeV/u to an isocenter with irradiation angles of over 0-360 degrees, and is further capable of performing three-dimensional raster-scanning irradiation. The combined-function superconducting magnets were employed for the rotating gantry. The superconducting magnets with optimized beam optics allowed a compact gantry design with a large scan size at the isocenter; the length and the radius of the gantry are approximately 13 and 5.5 m, respectively, which are comparable to those for the existing proton gantries. The total weight of the gantry is estimated to be approximately 300 tons, which is roughly half of the existing gantry for carbon radiotherapy. A construction of the gantry structure begun since early 2014, and the installation of the entire gantry system to the Heavy Ion Medical Accelerator in Chiba (HIMAC) complex at National Institute of Radiological Sciences (NIRS) completed by the end of September, 2015. Beam commissioning subsequently begun since October, 2015, and carbon beams, as accelerated by the HIMAC upper synchrotron, having kinetic energy of between 430-48 MeV/u were successfully transported with the rotating gantry to the isocenter. The size and shape of the beam spots at the isocenter were finely tuned over various combinations of the beam energies and the gantry angle. We will present the recent progress as well as the current status of the superconducting rotating-gantry. | |||||
