Abstract :
Cumulative beam breakup in linear accelerators has been studied for the case of infinitely short bunches. While this model is appropriate for high energy accelerators, in high-current ion accelerators the bunch length can occupy a significant fraction of an RF period of the deflecting mode. A semianalytic model has been developed to study and predict beam breakup in the case of nonzero bunch length and arbitrary bunch shape. Simulations of steady-state bunch distortion are presented, and the role of focusing in controlling beam breakup with bunches of nonzero length is illustrated.<>
