Colloquia Series Trinity Term 2016: Professor Bruce Remington - “Frontier Science on the National Ignition Facility (NIF)”

Martin Wood Lecture Theatre

The combination of high energy density (HED) facilities around the world spanning microjoules to megajoules, with time scales ranging from femtoseconds to microseconds, enables new regimes of plasma science to be experimentally probed. The ability to shock and ramp compress samples at Mbar pressures and simultaneously probe them allows dense, strongly coupled, Fermi degenerate plasmas relevant to planetary interiors, as well as solid-state lattice dynamics and plastic flows, to be studied. Shock driven hydrodynamic instabilities evolving into turbulent, high Reynolds number flows relevant to the dynamics of exploding stars are being probed. High temperature, high velocity interpenetrating flows are being probed for evidence of astrophysical collision less shock formation. Turbulent, high magnetic Reynolds number flows are being experimentally generated to look for evidence of the turbulent magnetic dynamo effect. The physics and dynamics of imploding plasma systems reaching ultrahigh densities and pressures of tens to hundreds of Gbar for inertial confinement fusion and basic science represent a central research focus area. And experiments to probe thermonuclear reactions in dense hot plasmas relevant to stellar interiors are starting to emerge. A selection of examples providing a compelling vision for frontier plasma and materials science in the coming decade will be presented.

Tea will be served in the Common Room after the event at 4.30 pm
