The mechanisms underlying the fast ion transport induced by MHD instabilities, such as Edge Localized Modes (ELMs) and externally applied Magnetic Perturbations (MPs) will be studied through innovative diagnosis techniques developed at the University of Seville and the Centro Nacional de Aceleradores (CNA) in Seville, Spain and employed in different fusion devices such as ASDEX Upgrade (Germany) and MAST Upgrade (UK).
The meeting was divided into four topical areas; linear and non linear benchmarking of Alfven eigenmode codes, ITER fast particle diagnostics and 3-D magnetic-field effects on fast ion confinement.
When a fast ion penetrates in matter, it loses its kinetic energy due to successive collisions with the atoms in the matter along its path, and finally stops.
It introduces the concept of two classes of receptor (the fast ion channel linked receptor and the G-protein linked receptor) and subsequently gives a detailed account of each.
They cover machine architecture and objectives; a magnetohydrodynamic description of the equilibrium and heating of the thermal plasma; Alfven cavity modes, fast ions, alpha particles, and diagnostic neutral beams; turbulent transport from the temperature gradients; operational regimes and their properties; transport barriers and edged localized modes control; steady-state operation; plasma diagnostics; plasma facing components and plasma-wall interaction physics; and the broader approach and tritium breeding blankets.
The first region is region of slow ions and the third region is of faster electrons, whereas the central region is of fast ions and slow electrons.
