  A heavy-ion accelerator complex is being designed for rare isotope beam production utilizing both in-flight fragmentation and ISOL methods in Korea. The project had been planned with conceptual design efforts, and officially launched in January this year with full funding promised. The driver accelerator is a superconducting linac with a beam power of 400 kW. The uranium beam, which is a primary beam for projectile fragmentation, is to be accelerated to 200 MeV/u. The in-flight fragment separator can be divided into pre and main separators. The target system and beam dump to handle the full beam power are located in the front part of the pre-separator, and are being studied using various codes such as PHITS and ANSYS considering issues especially related to radiation damage and shielding. Beam optics design was performed in the previous conceptual study, and further optimization is under way. The separator will be composed of large aperture superconducting quadrupole magnets and conventional dipole magnets, and prototyping of the superconducting magnet is planned. The status of the design efforts will be presented.
