Dynamic compression offers a route to extreme conditions of pressure and temperature that go beyond what is possible today by static compression. Exotic states of matter can be attained, such as Warm Dense Matter, relevant for planetary science, for the description of the interior of the planets and extrasolar planets, fundamental science, to constrain theoretical models, and energy science, for Inertial Confinement Fusion.
In more moderate conditions, dynamic compression can be used to look at the behavior of matter and materials under high strain rates that can strongly differ from the static case. This area of research also encompasses industrial processes such as laser machining or synthesis of new materials.
In the recent years shock-induced dynamic compression has witnessed a revolution thanks to the coupling of powerful lasers or other shock-generating devices to X-rays brilliant probes, opening new exciting opportunities for the scientific community.
The aim of the workshop is to gather scientists, both from the static and dynamic extreme conditions community, to discuss recent results and new scientific frontiers that can be explored thanks to this combination. This meeting is intended to inspire new projects and to offer a ground for future collaborations in view of the opening of the High Power Laser Facility at the ESRF, coupling a nsec, 100J laser to time-resolved X-ray Absorption, foreseen for September 2021 (proposal deadline 30th march 2021).
Time resolved X-ray diffraction (XRD) and X-ray imaging (XRI) coupled to dynamic compression experiments at the ESRF will be covered as well and plans for a future extension of HPLF (HPLF-II) to other X-rays techniques – XRD, XRI and X-ray emission spectroscopy – will be presented.
The main topics will cover:
– Planetary science: structure, evolution, geodynamics of planets, space impacts
– Warm dense matter: equation of state and phase diagram
– Behaviour of matter under high strain rates, comparison to static compression
– Synthesis of new materials, new chemistry
– Ab initio simulations for matter under extreme conditions
