Description
We propose a new class of compact superconducting cyclotrons based on the stripping of H3+ ions. In this method, H3+ ions are accelerated and pass through a thin carbon foil, where the electrons are removed to produce three protons per ion. Compact cyclotrons require high magnetic fields, which makes H- acceleration impractical; H3+ ions, however, can possibly tolerate much higher fields and are therefore suitable for this approach. The stripping technique offers very high extraction efficiency, enables variable-energy proton beams, and allows simultaneous delivery to multiple production targets. These features make such machines highly attractive. We aim at proton energy of 70–150 MeV and proton current of ~1.0 mA, which remains largely undeveloped worldwide. Our study focuses on beam dynamics, particularly the large acceptance required for high-intensity beam and feasibility of single-turn extraction to minimize beam losses. A baseline design and preliminary results are presented.
