Description

Designing modern charged-particle accelerators requires a detailed analysis of beam dynamics that accounts for the collective effects limiting the achievable parameters of the facility. Accountability of the fields induced by a high-brightness beam in the linear accelerator-injector of a free-electron laser is of particular importance, since these fields largely determine the final emittance and the energy spread, leading to beam instabilities. In the present work, based on numerical simulations when using a semi-analytical approach, the Green’s function of the wake potential for the regular section of the SYLA linear accelerator-injector has been obtained; the given function is intended for subsequent calculations of the longitudinal and transverse beam dynamics.
