Recent Progress on HIMAC for Carbon Therapy

An impressive advance of the carbon-ion therapy using the HIMAC has been supported by a highreliability operation and a development of accelerator technologies. Based on the development of the accelerator-technology as well as the progress on the HIMAC treatment, we have proposed the new treatmentfacility project for the further development of heavy-ion therapy. The study and R&D works for this project have seen successful progress, and the facility has been constructed since February 2009.
