Accurate Multipole Field Reconstruction Methods Based on 3-D Electromagnetic Field Simulation Results

This paper proposes the extraction of surrogate field models from 3-D electromagnetic simulation results, for use in a Vlasov beam-dynamics code. Each accelerator component is represented by a dedicated surrogate field model based on a series expansion of its 3-D field distribution. The obtained beam-dynamics simulation results are validated against a particle-in-cell tracking code that integrates a 3-D field distribution of the corresponding accelerator component.
