ED3310 Plasmavågor, avancerad kurs 6,0 hp

Plasma Waves, Advanced Course

This course should provide the theoretical basis for wave propagation in a hot plasma, including linear mode conversion. The student should be able to describe how waves affect the distribution function of resonant species and conditions for instabilities in velocity space.
