The Integrated Map and Particle Accelerator Tracking (IMPACT) code suite was originally developed to model beam dynamics in ion linear accelerators. It has been greatly enhanced and now includes a linac design code, a 3D rms envelope code and two parallel particle-in-cell (PIC) codes IMPACT-T, a time-based code, and IMPACT-Z, a z-coordinate based code. Presently, the code suite has been increasingly used in simulations of high brightness electron beams for future light sources. These simulations, performed using up to 100 million macroparticles, include effects related to nonlinear magnetic optics, rf structure wake fields, 3D self-consistent space charge, and coherent synchrotron radiation (at present a 1D model). Illustrations of application for a simulation of the microbunching instability are given. We conclude with plans of further developments pertinent to future light sources.
