| Abstract | In order to further improve high-resolution imaging at free-electron laser sources we developed an x-ray microscope based on beryllium compound refractive x-ray lenses (Be-CRLs), which is especially optimized for the XFEL environment and provides focusing capabilities down to 100nm and even below. In a first experiment, carried out at the Matter in Extreme Conditions (MEC) endstation of the LCLS, these optics were characterized by ptychographic scanning coherent microscopy and their performance was investigated by direct imaging of shock waves in different materials. The shock wave was induced by a 150ps laser pulse (wavelength λ = 800nm, energy E = 130mJ). The evolution of this shock wave was then monitored with the x-ray FEL-pulse by magnified phase contrast imaging. With the CRL optics, x-ray beam sizes in the sub-100 nm range are expected, leading to a similar spatial resolution in the direct coherent projection image. In this contribution we report on the current status of the instrument and show first analysis results of phase contrast imaging of shock waves in matter. |
