	To produce rare isotope beams, in-flight fragmentation method utilizing a thin target and heavy-ion primary beam can be used. The existing facilities provide the maximum primary beam power of a few kW, while the next generation facility is planned to use hundreds of kW of 238U beam.

The high-power target studied is made of multi-slice rotating graphite to enhance radiation cooling. The total target thickness is roughly 2 mm with more than 10 slices. The resultant power density inside the target reaches above 50 MV/cm³. Numerical simulation for thermo-mechanical analysis has been performed using PHITS and ANSYS for single and multi-slice targets.

To produce rare isotope beams, in-flight fragmentation method utilizing a thin target and heavy-ion primary beam can be used. The existing facilities provide the maximum primary beam power of a few kW, while the next generation facility is planned to use hundreds of kW of 238U beam. We are designing a rare-isotope beam facility, which can provide U beam with the maximal power of 400 kW at the energy of 200 MeV/u. The high-power target studied is made of multi-slice rotating graphite to enhance radiation cooling. The total target thickness is roughly 2 mm with more than 10 slices. The resultant power density inside the target reaches above 50 MV/cm³. Numerical simulation for thermo-mechanical analysis has been performed using PHITS and ANSYS for single and multi-slice targets. Also, empirical test was made using 70-keV electron beam for a single-slice rotation target with the thickness of 0.2 mm. The results of simulation and e-beam tests will be presented.
