Abstract
Structure mode frequency spreads are shown to have a rather different influence on beam breakup growths than betatron frequency spreads. Analytic and numerical studies show that a finite spread in the breakup mode frequency leads to an algebraic decay of the beam breakup instabilities even if the quality factor Q →∞. Asymptotic formulas and the time scale for this phase mixing to occur are presented. Effects of stagger tuning are examined numerically
