Third generation synchrotron light sources provide hard X-rays with high photon flux, high degree of spatial coherence, ~100 ps pulse widths and megaHertz (MHz) repetition rates. The exploitation of these properties is an important key to probe transient in-material processes, which evolve on timescales governed by material sound speeds in the order of km/s (μm/ns), in optically opaque objects.

In this webinar hosted by the Gamma, X-Ray and Extreme UV Optics Technical Group, Dr. Margie Olbinado from the European Synchrotron Radiation Facility (ESRF) will discuss how MHz frame rate XPCI is a powerful diagnostic tool to observe instantaneous velocities and internal structures, which cannot be obtained from X-ray attenuation-contrast imaging and cannot be probed, or only partially probed, using conventional ultra high-speed optical shadowgraph techniques. The importance of multiple-frame recording to observations of stochastic transient processes which are impossible to be realized using single-shot or stroboscopic XPCI will be highlighted during the webinar.

What You Will Learn:

  • The development of real-time X-ray phase-contrast imaging (XPCI) with single-pulse temporal resolution and multiple-frame recording up to MHz frame rates at the ESRF
  • How to optimize image detection and visualizations of various transient processes such as crack propagation in glass, explosion during electric arc ignition in fuse, laser-induced micro-cavitations and jetting in water, and laser-shock-induced compression in polymeric foam

Who Should Attend:

  • People interested in x-ray optics and instrumentation for large scale facilities
  • Anybody who is interested in the development of ultra-fast short wavelength sources
