Book Description
A number of topics in nonlinear and linear instability theory are covered in this report. The nonlinear saturation of the dissipative trapped electron instability is evaluated and its amplitude compares well with existing experimental observations. The nonlinear saturation of the drift cyclotron loss-cone mode is carried out for a variety of empty loss-cone distributions. The saturation amplitude is predicted to be small and stable. An improved linear theory of the collisionless drift instability in sheared magnetic fields yields the surprising result that no instability occurs for a wide range of parameters. Finally, the bump-on-tail calculation is shown to be unchanged by some recent results of Case and Siewart, and a rough time scale is established for the transition from the O'Neil trapping regime to the final time-asymptotic result.

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.
