Abstract:
How well we can confine heat and particles in a nuclear fusion reactor largely determines its efficiency. This means that the study of heat and particle transport is one of the most important topics in nuclear fusion research. This ranges from running extremely large gyrokinetic codes to extracting key physical parameters characterizing the heat transport from measurements. This talk discusses the latter introducing old strategies and new strategies to extract these key physical parameters from measurements such as the diffusion coefficient. These new strategies are based on system identification techniques adapted for partial differential equations treated in the frequency domain.
