Abstract

We will report on partially coherent undulator radiation simulations performed for the Hard X-ray Nanoprobe (HXN) beamline of NSLS-II with electron beam and X-ray optics instabilities taken into consideration. RF BPM and XBPM data were used to estimate values of these positional and angular instabilities for the partially coherent X-ray emission and propagation calculations with SRW code. These calculations allowed us to determine time-varying (due to the instabilities) intensity distributions and other characteristics of the X-ray radiation at important beamline locations, and estimate impacts of the instabilities on experimental data from coherent diffraction imaging experiments at HXN.
