Force Balance and Ion Particle Transport Differences in High and Low Confinement Tokamak Edge Pedestals
(Georgia Institute of Technology, 2010-11-22)
The various terms in the radial force balance in the edge plasma are evaluated using experimental data from the low (L) and high (H) confinement phase of a DIII-D [J. Luxon, Nucl. Fusion 42, 614 (2002)] discharge in order ...
Evolution of the H-mode edge pedestal between ELMs
(Georgia Institute of Technology, 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 ...
Tutorial: Principles and Rationale of the Fusion-Fission Hybrid Burner Reactor
(Georgia Institute of Technology, 2011-09-13)
The potential advantages of Fusion-Fission Hybrid (FFH) reactors (relative to critical fast reactors) for closing the back end of the nuclear fuel cycle are discussed. The choices of fission and fusion technologies for FFH ...
The effects of rotation, electric field, and recycling neutrals on determining the edge pedestal density profile
(Georgia Institute of Technology, 2010-05-19)
The edge density profile is calculated from the continuity and momentum balance equations, using experimental electric field and rotation velocities and a calculated recycling neutral source, to evaluate the relative ...

The Effect of Ion Orbit Loss and X-Loss on the Interpretation of Ion Energy and Particle Transport in the DIII-D Edge Plasma
(Georgia Institute of Technology, 2011-10-14)
Calculation models are presented for treating ion orbit loss effects in interpretive fluid transport calculations for the tokamak edge pedestal. Both standard ion orbit loss of particles following trapped or passing orbits ...
The effect of rotation and viscous heating on the interpretation of experimental heat diffusivities in the edge pedestal
(Georgia Institute of Technology, 2010-05-17)
A formalism is presented for evaluating the effect of plasma rotation, via viscous heating, on the interpretation of thermal conductivities from measured temperature and density gradients in the edge pedestal. An application ...
Non-Diffusive Transport in the Tokamak Edge Pedestal
(Georgia Institute of Technology, 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. ...
