How to calculate the neoclassical viscosity, diffusion, and current coefficients in general toroidal plasmas [PDF]
How to calculate the neoclassical viscosity, diffusion, and current coefficients in general toroidal plasmasA novel method to obtain the full neoclassical transport matrix for general toroidal plasmas by using the solution of the linearized drift kinetic equation with the pitch-angle-scattering collision operator is shown. In this method, the neoclassical coefficients for both poloidal and toroidal viscosities in toroidal helical systems can be obtained, and

Kinetic Energy Principle And Neoclassical Toroidal Torque In Tokamaks [PDF]
, 2011 It is shown that when tokamaks are perturbed the kinetic energy principle is closely related to the neoclassical toroidal torque by the action invariance of particles.

Experimental Investigations of Magnetohydrodynamic Plasma Jets [PDF]
, 2009 This thesis primarily focuses on understanding the plasma behavior during the helicity injection stage of a pulsed spheromak experiment. Spheromak formation consists of a series of dynamic steps whereby highly localized plasma near the electrodes evolves

Nuclear Fusion, 2016 Abstract A model-based feedback system is presented to control plasma rotation in a magnetically confined toroidal fusion device, to maintain plasma stability for long-pulse operation. This research uses experimental measurements from the National Spherical Torus Experiment (NSTX) and is aimed at controlling plasma rotation using two ...
