  A superconducting triple-spoke cavity as a rebuncher for very heavy ion beams such as uranium at β=0.303 for RIKEN RI-beam factory is designed. The required total gap voltage is 3 MV. In this design, thick ribs (25 mm) are placed on the both ends of cavity so that the deformation caused by pressure of liquid helium is less than 0.5 mm. A copper test model with one spoke is designed to be fabricated using the same technique as that for Nb cavity. The detailed design will be presented.
