Based 10 years experience of carbon therapy at HIMAC(Heavy Ion Medical Accelerator in Chiba),the new facility project has been in progress at NIRS.This project aims to provide the hospital-based carbon therapyfacility for the benefical treatment around Japan.In the new facility,it is required for the synchrotron to accelerate carbon ions forom 4MeV/u of injection energy to 400MeV/u.the design of the synchrotron was carried out according to the leading design strategies,which are 1)compactness, 2)high reliability and 3)low cost.For this purpose,at the HIMAC,we have carried out following machine studies: a)Macvhing of slowly extracted beam with transport line, b)Reasonance characteristics and beam lifetime, and c)Reproducibility of beam performance.In this paper,the design of the synchrotron dedicated for carbon therapy based on the machine study by HIMAC and the results of the studies are presented.
