A facility for heavy-ion radiotherapy is very large and the introduction cost is also high. National Institutes for Quantum and radiological Science and Technology (QST) has developing a next generation facility for heavy-ion radiotherapy, it is called quantum scalpel. The cost and size of devices are reduced by downsizing a synchrotron using superconducting technology and an injector using laser-accelerated technology. To realize the quantum scalpel, however, a short high energy beam transport system (HEBT) and a compact superconducting rotating-gantry are needed as well. In this study, we designed the optics of HEBT and the rotating-gantry for quantum scalpel. Optical conditions at an isocenter must be
matched for all beam energy used in heavy-ion therapy. We designed the optics of HEBT and the rotating-gantry in case of two energy conditions (430 MeV/u and 56 MeV/u), and device layout to reduce a footprint. We report results of the
optics design of HEBT and the rotating-gantry for the quantum scalpel.
