Description
The results on ion beam dynamics investigation in modular accelerating systems are presented. Beam dynamics in the systems, comprised of short independently phased cavities like quarter-wave (QWR), half-wave (HWR) or interdigital H-type (IH) cavities is characterized by the influence of additional fast field harmonics, periodic with the cavity spacing. These harmonics have an effect on longitudinal and transverse beam dynamics and thus on the beam quality. To take into consideration these harmonics fast oscillation averaging method is proposed. This method of beam dynamics investigation allows one to consider the beam moving in the equivalent effective potential, having the terms of average potential and terms with averaged electric and magnetic field fast harmonics. Analysis of effective potential function helps one to find transverse and longitudinal oscillation frequency tunes and to specify longitudinal acceptance of the cavity section.
