Book Description
Research has been carried out in two broad areas, nonlinear saturation of instabilities in collisionless plasma and incorporation of important physical phenomena into linear stability theories appropriate to Tokamaks. The nonlinear work has established a general technique for dealing with the singular functions which arise and is now applied to the collisionless drift, the dissipative trapped electron in linear geometry and the drift cyclotron loss cone. Multimode problems are under study. The linear theory includes the influence of resonant electrons on the trapped electron instability in sheared magnetic fields. A further calculation includes the collisional broading of the untrapped electron response. Finally a general technique is developed for calculations when there are collisions and the product of the poloidal wave number and ion gyroradium is not necessarily small.

Linear and Nonlinear Kinetic-stability Studies in Tokamaks

Book Description
This paper presents results of theoretical investigations on important linear kinetic properties of low frequency instabilities in toroidal systems and on nonlinear processes which could significantly influence their impact on anomalous transport. Analytical and numerical methods and also particle simulations have been employed to carry out these studies. In particular, the following subjects are considered: (1) linear stability analysis of kinetic instabilities for realistic tokamak equilibria and the application of such calculations to the PDX and PLT tokamak experiments including the influence of a hot beam-ion component; (2) determination of nonlinearly saturated, statistically steady states of three interacting drift modes; and (3) gyrokinetic particle simulation of drift instabilities.
