Detailed measurements of the magnitude and location of volumetric recombination occurring in the detached divertor of Alcator C-Mod tokamak [I. H. Hutchinson et al., Phys. Plasmas 1, 1511 (1994)] are presented. The drop in divertor plate ion current

The kinetic theory of transport in an impure, partially ionized, edge plasma is developed. It is found that the thermal force between bulk ions and impurities is enhanced by the presence of neutral atoms, but the dynamical friction is not affected by

Analysis of the experimental data from tokamaks and linear divertor simulators leads to the conclusion that plasma recombination is a crucial element of plasma detachment. Different mechanisms of plasma recombination relevant to the experimental cond

Understanding the physics of divertor detachment is important since detached operation in ITER could reduce the target heat flux drastically, while aiding helium ash removal. In order to model detachment properly we have incorporated a parallel Navie

Radial profiles of the density of confined alpha particles with energies in the 0.15 to 0.6 MeV range are spectroscopically observed before and after a sawtooth crash in a TFTR deuterium-tritium plasma. A large drop in the core alpha density is seen,

We have simulated detachment in Alcator C-Mod, using an improved neutral fluid model. It features a parallel neutral momentum equation, fully coupled to the ions, allowing parallel plasma momentum to be converted into neutral momentum, which is dispe

We have simulated detachment in ITER, with the UEDGE code coupled to a Navier-Stokes neutral model, for realistic toroidal geometry and plasma parameters, with a heat flux of 100 MW into the outboard SOL. For a fixed fraction of carbon, corresponding

It is shown that any representation of the functional dependence of thermal fusion reactivity on plasma temperature can be rewritten in an exact alternative form as a power law function and the appropriate power exponent is given. Based on this alter
