Abstract

Third generation synchrotron radiation light sources are designed for the operation of undulators and wigglers which increase the brightness by several orders of magnitude compared to dipole radiation. The light is partially coherent - and diffraction effects, depth of field effects of the insertion devices and polarization characteristics should be taken into account for beamline design and for radiation characterization. In previous work a procedure for a wave-front transformation through synchrotron radiation beamlines has been derived. The code PHASE allows a detailed description of diffraction related problems. In this paper an improved integration algorithm for the transformation method is presented which reduces the cpu time by one order of magnitude. Furthermore, a stepwise transformation of the wave-front is introduced which makes possible the evaluation of the electric field distribution at the surface of an optical element and hence, the implementation of apertures, random slope errors or refiectivities.
