Influence of emittance on transverse dynamics of accelerated bunches in the plasma–dielectric wakefield accelerator

We study theoretically transverse dynamics of the bunch of charged particles with the finite emittance in the plasma–dielectric wakefield accelerator. Parameters of bunches are chosen the same as available from the 15 MeV Argonne Wakefield Accelerator beamline. The goal of the paper is to study the behavior of bunches of charged particles with different emittances while accelerating these bunches by wakefields in plasma–dielectric structures. Obtained results allow us to determine the limits of the emittance of the bunch where dynamics of the accelerated particles remains stable.
