ED3330 Transport Theory 8.0 credits

Transportteori

The course should provide a theoretical basis for classical, neo-classical and anomalous transport in major fusion devices as well as an understanding for the theory of plasma transport and current drive in tokamaks. Canonical profiles and other applications in space and finances are also discussed.
