摘要：
A small cyclotron (the "cyclotrino") was proposed for direct detection of radiocarbon in 1980 and has now detected radiocarbon at natural abundance. High resolution and background rejection are achieved in this cyclotron by acceleration of negative ions through many turns while operating at a high harmonic. This article details the analysis of ion motion in a small flat-field, electrostatically-focused cyclotron. Included are discussions of beam acceptance, axial and radial beam stability, and a detailed analysis of phase bunching and its effect on mass resolution.
