Application of modern mathematical concepts to plasma confinement
Abstract
Progress in three research areas has been achieved. (1) A new expression for the trapping probability for transitioning particles in asymmetric toroidal plasma confinement devices (e.g., stellarators and rippled tokamaks) has been derived. Comparison with numerical integrations shows that this new expression is more accurate than those of previous workers. (2) Simulations show that the dynamical enhancement of the turbulent diffusion coefficient over quasilinear observed in test particle simulations occurs also in self consistent plasma turbulence. (3) The simple method for calculating magnetic island widths discussed in the previous report has been published.
