Abstract The Kyoto University Research Reactor Institute is engaged in research on an accelerator-driven system (ADS) using the fixed field alternating gradient accelerator at the Kyoto University Critical Assembly. With the aim of achieving the high-energy neutrons anticipated in the actual ADS experiments, we propose the use of a new target concept (the multi-target) in this study. The conceptual design of the multi-target is numerically carried out, and the high-energy neutrons generated by the injection of high-energy protons at the multi-target are successfully measured using a liquid organic scintillator in the experiments. The conceptual design and effectiveness of the multi-target is confirmed by the obtained neutron spectrum and neutron yield in both the experimental and calculated results.
