The NSLS2_CHX Instrument

Coherent hard x-ray beamline @ NSLS II


  • Site: NSLS2
  • Author: Jana Baltser
  • Origin: NBI, BNL
  • Date: March 2011
  • Version: 0.2


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). 

Input parameters

Parameters in boldface are required; the others are optional.
