The NSLS2_CHX Instrument
Coherent hard x-ray beamline @ NSLS II
Identification

Description
This is a lay-out of the coherent hard x-ray (CHX) beamline at NSLS-II. Since the ray-tracing method doesn't allow to account for partial coherence of the undulator source, the best approximation was to use the gaussian photon beam and to neglect diffraction effects on apertures. The choice of the source sizes along with angular divergence corresponds to the situation of high emittance (e=0.99nm).
