Description
An in-flight fragment separator has been designed for the rare isotope science project (RISP) underway in Korea. The primary beam power is 400 kW at maximum, which is reflected on the radiation shielding and thereby on the separator design. The beam energy of 238U is 200 MeV/u and will be increased to 400 MeV/u. Maximum magnetic rigidity of the separator is set as 9.5 Tm. Development of the major components, which includes graphite target, beam dump made of Ti-alloy, and large-aperture superconducting magnets using LTS and HTS coils, has been made. As the building design starts, configuration of the separator was finalized and the layout of the separator facility has been detailed. Comparison study with different configurations of the separator was carried out in terms of enhancing momentum resolution and beam purity. The study results will be presented as well as overall progress in the component design and prototyping for the in-flight system.
