Design study of the injection and extraction systems for the RIKEN superconducting ring cyclotron

In the RI beam factory project, an intermediate-stage ring cyclotron and a six-sector superconducting ring cyclotron (IRC and SRC) are designed to boost the energy of the ion beams available from the existing RIKEN ring cyclotron (RRC). The output energies designed to the SRC are 400 MeV/u for light ions such as carbon and are 150 MeV/u for heavy ions such as uranium. In the present report, we describe the recent status of design study of the injection and extraction systems for the SRC.
