Missions
• Design/propose/perform experiments on the deposition of laser energy and parametric instabilities (Stimulated Brillouin Scattering, Stimulated Raman Scattering, Cross Beam Energy Transfer, and Two Plasmon Decay) in a 2w configuration and flat geometry, on compatible laser facilities (LULI, GEKKO).
• Design/propose experiments on the L4n installation at ELI with high cadence. The L4n installation will have, in the short term, the bandwidth capacity that would allow the comparative study of the mitigation of parametric instabilities and other effects of nonlinear laser-plasma interaction.
Activités
• In anticipation of designing the laser and targets for the Taranis project, anticipate the choice of the laser driver and the consequences in terms of the deposition and transport of laser energy and parametric instabilities (LPI).
• Support in the preparation, execution, and analysis of dedicated experimental LPI campaigns in the field of FCI [Parametric Instabilities/CBET/Electronic Transport].
• Design and monitoring of experiments with theoretical support (hydrodynamic simulation code, kinetic code, and wave coupling code); development of efficient and operational diagnostics in cadence.
Compétences
• Education: PhD in physics (knowledge in plasma physics is a plus)
• Experience: Proven skill in the use of scientific computing codes and experimental skills
Contexte de travail
• 2022: A historic milestone with the first controlled fusion reaction producing energy gain at National Ignition Facility (NIF) using Indirect Drive.
• Dynamics: Strong national and European involvement in fusion research.
• TARANIS Project: Initiated in 2024 by Thales, supported by the BPI France call for projects, and in collaboration with scientific partners such as CEA/DAM, CELIA, LULI, CPHT.
• The position will be based in Talence near Bordeaux, within the IFCIA team at the CELIA laboratory
• Supervised by a team including D. Raffestin (Celia, CESTA), P.-E. Masson-Laborde (CEA/DIF), E. D'Humières (Celia, CESTA), D. Batani (Celia), J.-L. Feugeas (Celia, CESTA), Ph. Nicolaï (Celia, CESTA), V. Tikhonchuk (Celia/ELI).
