• Evolution of the H-mode edge pedestal between ELMs 

      Stacey, Weston M.; Groebner, Richard J. (Georgia Institute of TechnologyAmerican Institute of Physics, 2010-08)
      The evolution of edge pedestal parameters between edge-localized modes (ELMs) is analyzed for an H-mode DIII-D [J Luxon, Nucl. Fusion 42, 612 (2002)] discharge. Experimental data are averaged over the same sub-intervals ...
    • Higher Order Approximations of the TEP Method for Neutral Particle Transport in Edge Plasmas 

      Stacey, Weston M.; Zhang, Dingkang; Mandrekas, John (Georgia Institute of TechnologyAmerican Institute of Physics, 2006)
      Higher order approximations, which take into account the effects of angular anisotropy, spatial non-uniformity and energy dependence of the distribution of neutral particles, have been developed and implemented to extend ...
    • A neoclassical calculation of toroidal rotation profiles and comparison with DIII-D measurements 

      Stacey, Weston M.; Johnson, R. W.; Mandrekas, John (Georgia Institute of TechnologyAmerican Institute of Physics, 2006)
      Momentum and particle balance and neoclassical viscosity were applied to calculate the radial profile of toroidal rotation velocity in several DIII-D [J. Luxon, Nucl. Fusion, 42, 614 (2002)] discharges in a variety of ...
    • Non-Diffusive Transport in the Tokamak Edge Pedestal 

      Stacey, Weston M.; Groebner, Richard J.; Evans, T. E. (Georgia Institute of TechnologyInstitute of Physics, 2012)
      There are (at least) two classical mechanisms for non-diffusive transport in the edge plasma: i) particle “pinch” velocities due to forces such as VxB, and Er; and ii) outward drifts due to ion-orbit loss and X-transport. ...
    • Nuclear Mission for Fusion (Transmutation, fissle breeding and Pu dispostion) 

      Stacey, Weston M. (Georgia Institute of TechnologyElsevier, 2006)
      There are potential applications of fusion neutron sources to 'drive' sub-critical fission reactors to perform one or more possible 'nuclear' missions. Since only a fraction of the neutrons in these applications would be ...
    • Thermal Transport in the DIII-D Edge Pedestal 

      Stacey, Weston M.; Groebner, Richard J. (Georgia Institute of TechnologyAmerican Institute of Physics, 2006)
      A new procedure for inferring χ[subscript i,e] in the plasma edge from experimental data and integrated modeling code calculations has been developed which takes into account atomic physics and radiation effects and ...
    • Transmutation missions for fusion neutron sources 

      Stacey, Weston M. (Georgia Institute of TechnologyElsevier, 2005)
      There are a number of potential neutron transmutation missions (destruction of long-lived radioisotopes in spent nuclear fuel, ‘disposal’ of surplus weapons grade plutonium, ‘breeding’ of fissile nuclear fuel) that perhaps ...
