MSEE Research Published in Journal of Applied Physics

Research from MSEE URA Research Area 4: Photon Material Interactions was recently published by the Journal of Applied Physics. The article, titled “Time Resolved X-ray Diffraction in Shock Compressed Systems”, can be found in print (Vol.129, Issue 4) and online

In the paper, the authors give a perspective on the topic of time resolved x-ray diffraction in shock compressed systems with the goal of highlighting results in this rapidly growing field and placing them in the context of what can be learned from these techniques. While the primary focus is on x-ray diffraction, other time resolved x-ray techniques are included as well.

“Time resolved x-ray diffraction is a key tool for characterizing the interaction of light with materials in shocked systems,” said LLNL physicist Harry Radousky, lead author of the paper.  “As the MSEE work moves forward, understanding the shock drivers and x-ray capabilities at the diverse set of facilities available will become an increasingly important planning feature both in RA4 as well as other connected research areas.”

Congratulations to MSEE URA PI Harry Radousky of Lawrence Livermore National Laboratory and his co-authors Michael Armstrong and Nir Goldman on this publication.

FIG. 3. Ultrafast laser-driven shock compression experiments with x-ray diffraction (XRD) at the Linac Coherent Light Source (LCLS) only require a small-scale sample. Short timescale experiments enable small-scale samples, which can significantly enhance throughput.
