What is it about?
The aim of this research is to characterize the parameters of various metals under extreme conditions, with pressures exceeding 10 kbar and temperatures reaching several eV. In our Plasma Physics and Pulsed Power laboratory, we generate these extreme conditions by rapid Joule heating thin metal wires in an underwater environment. This process involves current pulses lasting several hundred nanoseconds, with amplitudes in the hundreds of kiloamperes and current densities ranging from 10 to 100 MA/cm².

Why is it important?
This research serves as a benchmark for theoretical models investigating Equations of State and conductivity models, which are both used in laboratory astrophysics and inertial confinement fusion.
Perspectives
This project took many months to complete and involved intense experimental work, simulations, and theoretical modeling.
