An Overview of High Energy Density Sciences in HiBEF Project

This talk will give an overview of high energy density (HED) researches in the frame of Helmholtz International Beamline for Extreme Fields (HiBEF) project leading by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The HiBEF user consortium is aiming to contribute and operate different experimental setups at the HED beamline of the European XFEL with worldwide unique ultrashort and extremely bright X-ray flashes.
Three main kinds of HED experiments including relativistic laser solid targets interactions to understand the plasma heating and ionization dynamics, high energy long pulse laser shocked warm dense matters to understand the stellar structures, intense XFEL-matter interactions to understand the effect of crystal structure on the rapidly melting and heating process performed by our group at LCLS and SACLA will be reviewed in this talk. All these experiments take advantages of the ultra-short and intense coherent XFEL beam as a probe to achieve nanometer and femtosecond resolutions simultaneously. Furthermore, to design and under the HED experiments, we will also present the theoretical and simulation studies based on the particle-in-cell (PIC) code, atomic collisional- radiative code and density function theory (DFT) code.
