	In-flight fragment separator of the rare isotope science project (RISP) is a main device to produce isotope beams for nuclear science research and applications. The separator is divided into pre and main stages. The pre-separator contains a thin target to produce the isotope beam and beam dump to remove unreacted primary beam. The maximum primary beam power is 400 kW. As a result, radiation level is very high in the target area and some of the magnets will utilize high-Tc superconductor coils operating at 20-50 K to efficiently remove the radiation heat deposited on the coil. A major function of the pre-separator is to remove the primary beam, which is complicated by different charge states produced when the primary beam passes through the target and wedge-shaped energy degrader. Some detailed calculations in beam optics and on the layout of the major separator components have been performed using GICOSY and LISE++ considering contaminant isotope beams due to nuclear reactions. Simulation results and some prototyping works will be presented.

	The beam dump is a critical component for the in-flight fragment separator using high-power primary beams at the rare isotope science project (RISP) in Korea. The maximum beam power is planned to be 400 kW, and a third of the primary beam power deposits at the isotope production target and the rest are dissipated at the beam dump. The beam dump is designed to be a rotating water drum, which is movable in the perpendicular direction to the beam to select the isotope beam of interest. The main primary ion beam is U, and its range at the energy of 200 MeV/u is only a couple of mm after passing through the shell structure of the drum. This short range requires the internal structure to confine water on the wall and high-pressure water flow. Some detailed thermo-mechanical and thermo-fluid analysis has been done using ANSYS and other codes. In addition, we plan to set-up a test bench to validate the simulations and water cooling system. Progress in the design works will be presented.

The beam dump is a critical component for the in-flight fragment separator using high-power primary beams at the rare isotope science project (RISP) in Korea. The maximum beam power is planned to be 400 kW, and a third of the primary beam power deposits at the isotope production target and the rest are dissipated at the beam dump. The beam dump is designed to be a rotating water drum, which is movable in the perpendicular direction to the beam to select the isotope beam of interest. The main primary ion beam is U, and its range at the energy of 200 MeV/u is only a couple of mm after passing through the shell structure of the drum. This short range requires the internal structure to confine water on the wall and high-pressure water flow. Some detailed thermo-mechanical and thermo-fluid analysis has been done using ANSYS and other codes. In addition, we plan to set-up a test bench to validate the simulations and water cooling system.
