A Novel High-Energy Ion-Beam Driver and its Applications

Abstract

A novel medium-energy synchrotron capable of accelerating all ion species is proposed as an ion driver for exploring new paradigms in material science. All ions, including cluster ions in their possible and arbitrary charge state, are accelerated in an injector-free single accelerator. The principle of accelerator is based on that of the induction synchrotron, which has been recently demonstrated at KEK. Various high-energy ions provided from the ion driver will be used in a way of penetration through bulk materials leaving large substantial electroexcitation energy. Uniform or localized implantation of energetic ions into the materials are rather general but still attractive approaches to create novel materials, such as a shock absorbing alloy with a soft layer underneath hard surface.
