Description succincte (Anglais)	Two years ago, the HES-SO completed a one-year ESA/OSIP project showing that our 1 kW pulsed microwave lamp can produce plasmas that share significant characteristics with the weakly ionized molecular plasmas of hypersonic flows. This is due to Plasma Ball Formation (PBF), an acoustic confinement mode also observed by a team at UCLA. PBF was shown to be the basis for a new low-cost technique for measuring physical properties in relevant non-equilibrium conditions, despite the low power of the setup, which is in the kW range. The proposed project consists of the design, development and testing of an innovative facility that would complement existing ground-based hypersonic facilities by enabling realistic physical simulation of plasma such as encountered by a re-entry body. This will significantly accelerate the development of materials for reusable TPS1, as well as facilitating debris demise testing. In the longer term, this will also provide a new, highly reliable method of inspecting TPS components, such as a refractory tile, in situ on the spacecraft once returned to the ground after atmospheric re-entry.
