Heavy ion cancer therapy with the Heavy ion Medical Accelerator synchrotron in Chiba (HIMAC) has been administered to more than 10,000 patients since 1994. We started the heavy-ion cancer therapy using a 3D scanning irradiation
system in May 2011, at New Particle Therapy Research Facility in NIRS. To enhance the treatment quality by achieving a precise dose control, we have continued some R&Ds on HIMAC and its irradiation system including a superconductingrotating gantry. Since 2016, we have started developments of a compact superconducting rotating gantry and a compact superconducting synchrotron to be applied for a newly started project of a “quantum scalpel” that is a next generation of the heavy-ion cancer therapy machine. We also started R&Ds for the intensity modulated multi-ion therapy that is applied to improve outcomes of the refractory cancer treatment. This paper outlines those R&Ds as well as the present status of HIMAC accelerator facility.
