Influence of magnetic field directions inhomogeneity on longitudinal propagation of wave beams in axisymmetrical magnetic trap

摘要

In present communication analytical and numerical investigations of electromagnetic waves with frequency near electron cyclotron frequency propagation in axisymmetrical magnetic trap are presented taking into account variation of magnetic field direction using ray tracing formalism. Influence of magnetic field inhomogeneity on efficiency on electron cyclotron resonance heating of plasma in axisymmetrical magnetic trap is investigated. Obtained analytical results can explain numbers of experimental phenomena in electron cyclotron discharge in axisymmetrical magnetic traps experiments.
