X-ray phase contrast imaging as a plasma diagnostics technique — •Lisa Dietrich, Bernhard Akstaller, Stephan Schreiner, Veronika Ludwig, Max Schuster, Gisela Anton, and Stefan Funk — ECAP - Erlanger Centre for Astroparticle Physics, Universität Erlangen-Nürnberg, Erwin-Rommel-Str. 1, 91058 Erlangen, Germany

A single-shot x-ray phase-contrast imaging technique with short exposure time allows to capture sharp images of fast dynamic processes, like laser-produced plasma shock-waves in high-energy density pump-prope experiments. Using grating-based x-ray phase-contrast imaging as a measurement technique, allows to determine the projected electron density distribution of a sample with a single acquisition. In this talk the methodology of grating-based phase-contrast imaging and its ability to retrieve electron density distribution is introduced. Further, the concept of a portable grating-based phase-contrast imaging setup is explained, which allows to adjust the interferometer at low repetion rate backlighter sources within a reasonable time using a fast-alignment method.
