Development work on the SRC, which is the world's first ring cyclotron utilizing superconducting technology, for the heavy-ion accelerator RIBF being constructed by RIKEN has now been completed. The SRC is the final booster in the RIBF accelerator complex and is capable of accelerating even heavy ions such as uranium up to 350 MeV/nucleon. Based on its expertise and many years of experience in manufacturing large superconducting magnets, Hitachi, Ltd. was commissioned to develop and fabricate a total of six sector magnets, the most critical subsystem of the SRC. Constituent parts of the sector magnets were completed at the end of March 2003, and after delivery to the site and installation, all superconducting coils achieved their rated current without quenching in the fall of 2005, and the SRC delivered its first beam in December 2006.
