Application of the cyclotron auto-resonance acceleration to a proton acceleration

In recent years, there has been a demand for a high intensity accelerator having high power efficiency for massively and inexpensively producing a short life RI, which is expected to be used for treatment of advanced cancers is increasing. We aim to develop an accelerator applying the cyclotron automatic resonance principle to acceleration of protons and helium ions. If it can be applied to protons and light ions, it becomes possible to realize a high intensity accelerator with high power efficiency suitable for RI production. We are planning to develop by analyzing the trajectory using the OPAL of the calculation code which was actually developed at the Paul Scherrer Institute in Switzerland and was used to design the actual accelerator.
