First-Principle Simulations of Electron-Bunch Compression Using a Large-Scale Liénard-Wiechert Solver

We present first-principle simulations of coherent synchrotron radiation (CSR) using the large-scale beam-dynamics program Lw3D [1] which solves for the Lienard-Wiechert fields in 3D using a macroparticle approach to represent an electron bunch. We have adapted Lw3D to include the bunch self-interaction via CSR field and simulated the resulting beam dynamics as the bunch travels throughout a dipole magnet. We compare our results with the 1D theory and explore the self-consistent effects when simulating a bunch undergoing bunch compression in a chicane beamline under consideration at the Argonne Wakefield Accelerator.
