A medium-energy synchrotron capable of accelerating all ion species based on a novel technology of the induction synchrotron* has been proposed as an all-ion accelerator (AIA)**. The AIA without any specific injector employs a strong focusing lattice and induction acceleration, driven by novel switching power supplies. All ions, including cluster ions with any charge state, are accelerated in a single accelerator. A plan to modify the existing KEK 500 MeV Booster to the AIA is under consideration. Its key aspects, such as an ion-source, a low-field injection scheme and induction acceleration***, are described. Deep implant of moderate-energy heavy ions provided from the AIA into various materials may create a new alloy in bulk size. Energy deposition caused by the electro-excitation associated with passing of swift ions through the material is known to largely modify its structure. The similar irradiation on metal in a small physical space of less than a mm in diameter and in a short time period less than 100 nsec is known to create a particularly interesting warm dense-matter state. The AIA capable is a quite interesting device as a driver to explore these new paradigms.
