High Energy Density Physics (HEDP) Laboratory

   
High Energy Density Physics Laboratory

The HEDP group performs computer simulations and experiments at cutting edge laser facilities around the world, in order to study interactions of ultraintense lasers with solid and warm dense targets. Most experiments relate to the making of electron or proton beams that are able to ignite fuel via Fast Ignition; an advanced approach to Inertial Confinement fusion. Some of the issues we investigate include physics of laser/plasma interactions, improving laser-to-beam energy efficiency via target design, particle transport in warm dense matter, beam/plasma instabilities, and energy deposition in dense matter. The HEDP Group also studies Z-pinch plasmas- plasmas confined by an electrical current that runs along the z-axis- driven by pulsed power generators. These plasmas have applications in Inertial Confinement Fusion (ICF) and astrophysical plasmas. Experiments are carried out on campus using state of the art compact linear Transformer drivers.

Pulsed Power Plasmas

   
Pulsed Power Plasma Image

The Pulsed Power Plasmas group investigates the properties of plasmas generated using high power electrical pulses, and how these can be used to investigate outstanding issues in plasma physics. Pulsed power plasmas are often dense, fast-moving and strongly cooled, and experiments can be designed to examine a variety of topics. Of particular interest is the formation of flows and shocks in these plasmas, and how experiments can help understand aspects of star-formation and supernovae explosions.  In energy research, we investigate an approach to fusion energy called inertial confinement, and how this might be incorporated into a power station design. The group compares experimental data from our on-campus laboratory to those from collaborators’ experiments and sophisticated computer codes to unravel the key mechanisms behind these processes.

Laser Matter Interactions

   

Laser Matter Interactions

The Laser-Matter Interactions Group studies the interactions of high-energy short-pulse lasers with matter. Experimental studies are performed in the Laser Plasma and Laser Matter Interactions Laboratory, which houses several solid-state and gas lasers as well as an extensive suite of diagnostics. Applications of our work include soft xray light sources for next-generation semiconductor lithography, optics damage, surface patterning, LIBS (laser induced breakdown spectroscopy), PLD (pulsed laser deposition) and inertial fusion chamber dynamics.
