Title: Coherent Synchrotron Radiation Wake Fields with a Discontinuous Galerkin Method

Abstract:

Coherent synchrotron radiation (CSR) is an essential consideration in modern
accelerators, yet is often computationally difficult to accurately model. A common approach
used in simulating CSR effects uses the paraxial, or slowly-varying envelope approximation
with a simple constant cross-section approximation of the geometry. While these
approximations are often valid for the simulation of many accelerator components, it is
important to closely analyze the errors introduced by such approximations by comparing them
with wake field solutions obtained by full-wave electromagnetic field simulations. For this
application, the in-house code CSRDG (CSR with discontinous Galerkin) evolves Maxwell’s
equations the time domain after a curvilinear coordinate transformation and a Fourier series
decomposition in a transverse direction, is applied to a bunch compressor model.
