Current numerical packages containing CSR wake fields generally use 1D models, which can become invalid in electron beams with very high brightness. On the other hand, the existing 2D or 3D codes are often slow. Here we report DFCSR, a novel particle tracking code that can simulate 2D/3D CSR and space charge wakes in relativistic electron beams 2 or 3 orders of magnitude faster than conventional models like CSRtrack. We performed benchmark simulations based on FACET-II beams, where electron beams are compressed to reach 300 kA peak current. The tracking code is written in Python and C programming languages with human-friendly input styles and is open-sourced on GitHub. It can serve as a powerful simulation tool for the design of next-generation accelerators. PB - JACoW Publishing CP - Geneva, Switzerland ER -
