Improved models for synchrotron radiation sources in SHADOW

A technique to improve the description of synchrotron sources is proposed and applied to the ray tracing code SHADOW. Using a dedicated synchrotron radiation calculation code, it is possible to calculate the single electron emission, as well as the thick electron beam emission. Two methods will be introduced. The first simulates synchrotron radiation using the spatial electron distribution for the positions of the rays and the thick electron beam spectral-angular distribution in the far field for their directions and their energies. The second method derives the variation of the single electron spectral-angular distribution with respect to the electron direction and the electron energy, and simulates the rays emitted by each electron. A preprocessor for SHADOW has been developed to read the intensity distribution from an HDF5 file generated by SRW. The final rays have been used to simulate future beamlines and have been cross checked with the wavefront propagation method.
