Abstract
In this work, we demonstrate simultaneous phase-contrast imaging (PCI) and X-ray diffractionfrom shock compressed matter at the Matter in Extreme Conditions endstation, at the LinacCoherent Light Source (LCLS). We utilize the chromaticity from compound refractive X-ray lensesto focus the 24.6 keV 3rd order undulator harmonic of the LCLS to a spot size of 5lm on target toperform X-ray diffraction. Simultaneous PCI from the 8.2 keV fundamental X-ray beam is used tovisualize and measure the transient properties of the shock wave over a 500lm field of view.Furthermore, we demonstrate the ability to extend the reciprocal space measurements by 5 Angstroem, rel-ative to the fundamental X-ray energy, by utilizing X-ray diffraction from the 3rd harmonic of theLCLS.
