Welcome to the Pulsed Power Plasmas Group
The Pulsed Power Plasmas Group make uses of experimental facilities both on and off campus to investigate the application of pulsed power generated plasmas in basic plasma science, laboratory astrophysics, High Energy Density science and Inertial Confinement fusion.
The group also has access to 3-dimensional resisitive MHD and kinetic codes, which are continually benchmarked to the experiments. This close co-ordination allows more accurate design and interpretation of the experimental programs.
The group is led by Dr Simon Bott-Suzuki, and is part of the UCSD Center for Energy Research. A summary of current research projects can be found on the Projects page.
Dr Bott-Suzuki recently delivered a Plenary talk on Pulsed-power Fusion Energy to an IFE workshop hosted by Lawrence Livermore National Laboratory - click here for a pdf of the talk

Plasmas generated using pulsed power
The plasmas we study are generated by rapidly heating solid metals or gases using short pulses of electricity. This is typically achieved using individual capacitors or capacitor banks charged to 10s of kilo-volts (kV) to give electrical pulses from 100ns to 1us in duration. These pulses can drive 50 kilo-amperes (kA) to several mega-amperes (MA) of current into the load.
Through ohmic heating, the load (often a thin metal wire or cylinder) goes through rapid melting and boiling. It is eventually hot enough (~100,000 C) for electrons to be removed from the resulting gas. This plasma can be directed using the magnetic fields generated by the current in various ways to allow us to study different topics
