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.

The Rare Isotope Science Project (RISP) got launched December 2011 which consists of In-Flight Fragmentation Facility and ISOL facility, providing uniques research opportunities in broad range of sciences. The superonducting driver linac can accelerate up to 200 MeV/u for uranium beam and up to 600 MeV for proton beam. The ISOL post linac which is also a superconducting linac. Design parameters and choices are presented.

Heavy ion beams of 400 kW and 70 kW are generated at the RISP by in-flight and ISOL methods, respectively. Front-End system in the RISP consists of 28 GHz superconducting ECR-IS with 10 keV/u, LEBT with two-bends and a multi-harmonic buncher, a RFQ with 81.25 MHz and 300 keV/u, and MEBT with two re-bunchers. The design studies have been performed to optimize the beam and accelerator parameters to meet the required design goals. It is shown that the front-end simulations results can provide the two-charge state beams up to uranium to upstream linac with the required beam emittances. In this paper, we present the design results for the front-end system and on the beam dynamics.
