Abstract:

The generation of unstable waves in the magnetosphere is reviewed, with emphasis on waves occurring near the trapped particles gyrofrequencies. Relativistic modifications to the basic theory are described. The evolution of trapped particles distribution diffusion is discussed, and the non linear theories of wave propagation and growth are invoked as the means whereby the evolution of the distribution functions can be studied. It is pointed out that, because of difficulties in the analytic theories, computer simulation may be the most certain technique for investigating effects of unstable waves on particles. Some particular unsolved problems are indicated, with special emphasis on trapping of artificially injected electrons. The development of a computer program which simulates actual physical processes in the magnetosphere is described. Author
