| Abstract: | Supersonic Rotation on the Maryland Centrifugal Experiment The Maryland Centrifugal Experiment (MCX) studies the confinement of plasmas and velocity shear stabilization of MHD instabilities. It does this by introducing a radial electric field of up to 9 kV in a magnetic-mirror geometry with up to 3 kG at the midplane and up to 19 kG at either mirror. The discharge produces a fully-ionized highly sheared plasma rotating at supersonic velocities in the azimuthal direction under the influence of J x B forces. This arrangement leads to a condition of ``centrifugal confinement'', in which the supersonic rotation creates an artificial gravity which draws the plasma away from the mirrors, closing the mirror loss cone. The large v_\phi shear stabilizes the plasma and enforces laminar flow. MCX has completed its main construction phase and is acquiring data, and the theory and simulations supporting the MCX centrifugal confinement scheme are presented with the data and analysis from its fi... |
