The Fusion and Astrophysical Plasma Physics Group within the Physics Department and the Center for Astrophysics and Space Sciences at the University of California, San Diego is led by Professor Patrick H. Diamond and consists of two research scientists-- Mikhail Malkov, Fred Hinton, and four graduate student researchers-- and is managed by an administrative assistant.
Up-gradient particle flux in a drift wave-zonal flow system - L. Cui, G.R. Tynan, P.H. Diamond and C. Brandt
We report a net inward, up-gradient turbulent particle flux in a cylindrical plasma when collisional drift waves generate a sufficiently strong sheared azimuthal flow that drives positive (negative) density fluctuations up (down) the background density gradient, resulting in a steepening of the mean density gradient. The results show the existence of a saturation mechanism for drift-turbulence driven sheared flows that can cause up-gradient particle transport and density profile steepening.
