Abstract : This report gives an overview of the experimental and theoretical research supported by ONR grant N00014-89-J-1714 from 1989 to 1995. The research focused on waves, transport, and equilibrium of magnetically confined single-species plasmas. Two new apparatuses were built: a laser-diagnosed ion apparatus targeted towards 'test-particle' measurements of cross-field transport from long-range ion-ion collisions; and a camera-diagnosed electron apparatus which gives quantitative data on 2-dimensional fluid instabilities, vortices, turbulence and relaxation processes. Theory work provided support for the experiments, and developed several fundamental plasma effects, including rotational pumping transport, a 2D stability theorem, waves in finite-size ion plasmas, and the structure of ion crystals. These results have been published in 57 journal articles and 5 Ph.D. theses.
