Research activities:
This group is mainly devoted to the theoretical study of various aspects of magnetic confinement, and to theoretical and experimental research in dense magnetised plasmas. Special emphasis is given to the study of the L-H mode transition mechanisms in toroidal plasmas, edge plasma physics and divertor plasmas. Regarding the latter two topics, the group is concerned with the role of neutrals and impurities in radiative instabilities, the cleaning effect of the scrape-off layer, and the achievement of detached mode. The foundations of current profile consistency, and plasma relaxation, in a more general sense, including the study of tearing modes, have been the subject of study for several years. Research is also being carried on the study of equilibria and stability of low aspect ratio tokamaks and multipole configurations. A 5KJ @ 37 kV dense plasma focus device, named Fuego Nuevo II has been in operation since September 1995, where studies on ion acceleration, hot-spots, and their role in neutron yield are being carried on. Yields of 108 neutrons per shot with anisotropies around 1.5 are usually observed.
