Title: Distribution of the Absorbed ECRH Power among the Electrons in a Plasma Heated by an Extraordinary Wave.
Authors: Erukhimov, V. L.; Semenov, V. E.
Abstract: A study is made of the one-dimensional linear problem of the absorption of the energy of an extraordinary wave propagating along a nonuniform magnetic field by a plasma in the ECR region. The plasma electrons are assumed to be nonrelativistic and are described by a collisionless kinetic equation. The distribution of the absorbed power among the electrons and the distribution of the self-consistent field over the confinement system are obtained. The conditions under which the ECRH power is distributed uniformly among the bulk electrons are determined. The limits of applicability of the locally nonuniform magnetic field approximation are established. The solutions derived are compared with the solution to an analogous problem with the collisional absorption mechanism. © 2001 MAIK “Nauka / Interperiodica”.
