Emittance growth in mismatched charged particle beams

A novel theoretical model of emittance growth in nonstationary charged particle beams that generalizes the previous theory of nonuniform charge distributions to include RMS mismatched and off-centered beams has been developed. The behavior of mismatched uniform beams in linear focusing channels, where no emittance growth occurs, is discussed. The results of the new theory are presented and compared with numerical simulation studies for RMS mismatched, nonuniform beams.<
