Dynamic Analysis of a Fusion System Using the System Transfer Function

A simplified approach to determine the dynamic and stability properties in a fusion system has been developed. It is based on the determination of the system transfer functions. A detailed analysis, which includes the interaction among alpha particles, electrons, and ions, shows that the system stability properties, in the sense of the operating conditions of plasma temperature and density in a point-kinetics model, can readily be determined without explicitly solving the time-dependent dynamic equations.
