This source model reads the dumped radiation field output from GENESIS 1.3 and samples it to be used
Genesis 1.3 is a simulation code to calculate
the performance of Free-Electron Lasers (FEL), where the kinetic energy of
electrons is transferred into a tunable, high-brightness radiation source (DESY,PSI).
Parameters in boldface are required;
the others are optional.
