EPP

The Enceinte à Plasma Pulsé (EPP) is an experimental facility developed for studying thermodynamic and transport properties of metals in the warm dense matter regime. The EPP is based on the pulse Joule heating technique, where micrometer thin metallic foils confined between two sapphire plates are heated by a microsecond electrical discharge. In-situ measurements provide access to electrical conductivity and thermodynamics properties such as dissipated internal energy variation, pressure and density. More precisely, relaxed states can be probed up to 1/10 of the initial density and for pressure reaching up to 5 GPa.
