Start-to-end simulation plays an important role in designing next generation light sources. In this paper, we present recent progress in further development and application of the parallel beam dynamics code, IMPACT, towards the fully start-to-end, multi-physics simulation of a next generation X-ray FEL light source. We will discuss numerical methods and physical models used in the simulation. We will also present some preliminary simulation results of a beam transporting through photoinjector, beam delivery system, and FEL beamlines.

	Funding: DOE Office of Science, Office of Basic Energy Sciences; NNSA. Synchrotron radiation is one of the most important and difficult to model phenomena affecting lepton accelerators. Large-scale parallel modeling provides a means to explore properties of synchrotron radiation that would be impossible to study through analytical methods alone. We have performed first-principles simulations of synchrotron radiation, using a Lienard-Wiechert approach, with the same number of simulation particles as would be found in bunches with charge up to 1 nC. The results shed light on the importance of shot noise effects, the amplification of coherent synchrotron radiation due to longitudinal microbunching, the interplay of electric and magnetic forces, and the limits of the widely used one-dimensional model.
