○題目(Title):
New regimes of high energy density science on the National Ignition Facility

●概要(Abstract):
Results from NIF Discovery Science will be presented. Examples include nuclear reactions relevant to stellar nucleosynthesis. [1] Equations of state at extreme pressures relevant to planetary and exoplanet interiors are being measured. [2] Studies of Rayleigh-Taylor instabilities at high Reynolds number, relevant to supernova explosions, are being studied. [3, 4] Experiments to study magnetic reconnection at HED conditions have been done. [5] High velocity, low density interpenetrating plasmas that generate collisionless astrophysical shocks, magnetic fields, and that accelerate particles relevant to cosmic ray sources are also being studied. [6] NIF experiments have demonstrated strong suppression of heat conduction in a replica of galaxy-cluster turbulent plasmas. [7]. Experiments relevant to turbulent star formation dynamics are underway on NIF. [8, 9] And relativistically hot plasmas are being generated and studied on the NIF ARC laser. [10]
