Title: New regimes of frontier science on the National Ignition Facility (NIF) laser
Abstract: A selection of results from the NIF Discovery Science program will be presented. Examples include nuclear reactions relevant to stellar nucleosynthesis. [1] Equations of state at very high pressures relevant to planetary cores, exoplanet interiors, brown dwarf interiors, and white dwarf envelopes are being measured, and show that ionization can significantly affect the compressibility of matter. [2-6] Studies of Rayleigh-Taylor instabilities and the generation of turbulence at high Reynolds number, relevant to supernova explosions, are being studied. [7-13] Relativistically hot plasmas [14,15] and target-normal sheath acceleration (TNSA) of protons [16-18] are being studied on the NIF ARC laser. Experiments to study magnetic reconnection at high energy densities are underway. [19] High velocity, low density interpenetrating plasmas that generate collisionless astrophysical shocks, magnetic fields, bursts of neutrons, and that accelerate particles relevant to cosmic ray generation are also being studied. [20-22] NIF experiments have demonstrated strong suppression of heat conduction in a replica of galaxy-cluster turbulent plasmas. [23] And with the achievement of ICF ignition demonstrated, [24] this opens up possible opportunities to study burning plasma dynamics relevant to astrophysical burn physics such as in Type-1A supernovae.
