    Les auteurs consacrent leur étude aux trois « gros » Tokamaks actuellement en cours de réalisation dans le monde : JET (CEE), TFTR (Etats-Unis) et JT 60 (Japon). Ils décrivent leurs objectifs respectifs, leurs paramètres ainsi que les caractéristiques attendues de leurs plasmas, l'accent étant mis plus largement sur le projet européen JET. Ils indiquent enfin les calendriers de réalisation et l'état d'avancement de ces installations

    RF Heating Experiments in the WEGA Tokamak

    No full text
    To the WEGA Tokamak plasma, up to 90 kW RF power near the lower hybrid frequency (500 MHz) have been applied using interna1 coupling structures. Measurements of electron temperature profiles by different methods are presented. It appears that the electrons do not absorb a significant fraction of HF power. Fast ions are produced during the HF which flux decays in about 100 µs. A bulk ion temperature increase of about 90 eV (or 60 %) is observed with a decay time after the HF is turned off of the order of 2 ms
