In 2010, a new particle therapy research facility connected to HIMAC was built, and we started heavy-ion radiotherapy using a 3D scanning irradiation system in 2011 and using a superconducting rotating gantry in 2017 at the new facility. In 2016, we began a project of "quantum scalpel", a next-generation heavy-ion radiotherapy machine that applies a compact superconducting synchrotron and rotating gantry currently under development. This paper outlines R&Ds for a new project and current facility as well as the present status of HIMAC.}, title = {放医研HIMACの現状報告}, year = {2022} }
