TL;DR: In this paper, a closed set of moment equations is presented for the time evolution of thermodynamic and magnetic field quantities which results from collisional transport of the plasma and two-dimensional motion of the magnetic flux surface geometry.

TL;DR: In this article, the full viscosity tensor for an axisymmetric toroidal plasma in the collisional regime (with strong rotation) is calculated, including gyroviscosity and O(e) poloidal variations over the flux surface, and the resulting viscous force is of sufficient magnitude to account for the radial transfer of toroidal momentum that must be inferred in order to explain the rotation measurements in tokamak experiments.

TL;DR: In this article, a collisional-regime theory for rotation and impurity transport in a tokamak plasma with strong, directed NBI and strong rotation (v ≈ vth) was extended to the plateau regime.

TL;DR: In this article, the Impurity Study Experiment (ISX-B) was extended to higher beam power, resulting in an expansion of the ISX-b operating space, and a linear relationship of energy confinement and plasma density was observed.

TL;DR: In this paper, the Balescu-Lenard kinetic equation is used to include collective effects through the dielectric constant and the theory is applied to the slowing down of fusion born alpha particles in a mirror-confined plasma and theory and numerical results are compared to previous treatments and corrections are found.
