"Particle acceleration in front of tokamak RF antennae"@en . "1686"^^ . . . . "1"^^ . "0"^^ . . "7"^^ . "7"^^ . . "A whole range of methods utilizing absorption of RF waves momentum or energy is applied for electric current generation as well as for additional heating of plasma in tokamaks. Because a high RF power is often used, the wave-plasma interaction can be accompanied by a number of non-linear effects. Commonly observed damages of limiter parts and divertor plates, which are connected directly waith the antenna by lines of force of the confining magnetic field, can be result of such an interaction. Theory developed in IPP Prague explains this undesirable phenomenon by acceleration of particles due to the processes taking place just in front of the antenna. Project proposed sets as a goal the experimental verification of this theory conclusions. The experiments will be carried out on Czech tokamak CASTOR and also in a broad international co-operation on the big superconducting machine Tore Supra in France."@en . "5886"^^ .
