Synopsis:

Advanced course on physics of thermonuclear fusion in the magnetic confinement of tokamaks. The course is focused on

the physics context, terminology and phenomenology of the subject so that students can substantially improve their understanding of physics background as well as their capacity to search for information and to work independently with scientific literature.
