Plasma Turbulence

Professor Barrett Rogers's research in theoretical and computational plasma physics addresses problems in turbulence, a ubiquitous feature of plasma systems. It can arise, for example, from non-uniformities in plasma flows, or be driven by instabilities arising from non-uniformities in the plasma density or temperatures. In magnetic fusion experiments, small-scale instabilities generate turbulence at small scales, which in turn transport plasma and heat from the core of fusion reactors to the walls. The convective losses generated in this way are among the greatest difficulties facing the design of a feasible fusion device.
