EURORIB'15

An in-flight fragment separator has been designed for the rare isotope science project (RISP) in Korea to provide rare isotope beams with worldwide users. The beam energy of 238U is 200 MeV/u in the initial phase and will be increased to 400 MeV/u so that we set the maximum rigidity to be around 9.5 Tm. The primary beam power is 400 kW at maximum, which is reflected in the radiation heating calculation and shielding design. The development of major components, which includes graphite target, beam dump made of water drum, and superconducting magnets using LTS and HTS, are underway. As the building design was started, the layout of the facility has been detailed with an architectural company. Although we finalized the overall configuration of the separator for the building, we continue to study different configurations of the separator. The overall progress of the in-flight system’s design and prototyping will be presented along with the results of beam optical study.
