【概要】
Warm dense matter (WDM) is ubiquitous throughout the universe and prevails in giant planet interiors, brown dwarfs and inertial-confinement fusion targets on the path to ignition. In WDM, equations of state, opacities and transport properties are governed by the dynamic structure factor which is often extracted from x-ray Thomson scattering (XRTS). However, the models used to infer density and temperature from XRTS spectra in laboratory WDM experiments have rarely been corroborated by momentum-resolved density-response measurements under independently diagnosed thermodynamic conditions. Establishing such a controlled, momentum-resolved, high-quality benchmark for standard WDM models has therefore remained an open challenge. In this talk, experimental platforms at the HED instrument of the European XFEL that are capable of attaining benchmark measurements of XRTS in WDM will be presented. Combining a range of spectroscopy developments, innovative target delivery, as well as the nanosecond DiPOLE laser to shock-compress matter leads to high signal-to-noise spectra with excellent statistics that serve as robust, model-discriminating benchmark data.
