Abstract

The possibility of the operation of a multistep trapping process in the interaction of the ions of a plasma with lower-hybrid waves, leading to the formation of a tail in the ion velocity distribution is investigated. Considering waves propagating perpendicularly to a homogeneous magnetic field, it is found that the spectral nature of the lower-hybrid excitation and the dependency of the perpendicular wave vector on the radial coordinate of the torus are the characteristics of the system which enable this cascading acceleration to take place. The conditions and limitations for the operation of this mechanism are discussed.
