| Research Abstract |
Plasma geometry, pressure and compressibility effects are found to have significant influence on the growth rates, saturation levels and evolution of energetic particle driven modes. However, the overall particle transport caused by these modes is found to be less sensitive to these effects. It is concluded that the form of the particle distribution function plays a more important role. New numerical methods are developed, which will be used to clarify the role of the distribution function in the future.
