Improvement of injection efficiency of carbon ions for medical synchrotron

Abstract

This paper describes a systematic study for optimization of the multi-turn injection effciency of carbon-ions for medical synchrotron. This is accomplished by optimizing tunes, bump-magnet parameters, and the number of turns required for injection. For selecting optimal tunes, a frequency map is investigated which reveals various resonances limiting the injection efficiency. The injection bump and the number of turns are optimized by tracking numerous particles up to a few thousand turns after injection. Space-charge effects are considered and found to be non-negligible at the chosen injection energy, 7 MeV/u.
