During the last two decades, NIRS has developed both the accelerator and beam-delivery technologies related to the carbon-ion RT, which has brought several carbon-ion RT facilities in Japan. At present, NIRS has developed a carbon-ion rotating gantry with the superconducting technology to be operated from 2016. As the future plan, NIRS has developed a direct acceleration system of positron-emission beams for verification on an irradiation field, and NIRS also just starts a design study of a superconducting synchrotron ring for carbon-ion RT.}, pages = {2812--2814}, publisher = {JACoW}, title = {RECENT PROGRESS AND FUTURE PLAN OF HEAVY-ION RADIOTHERAPY FACILITY, HIMAC}, volume = {IPAC}, year = {2014} }
