Quadrupole Antenna and Diagnostic Complex for Ion Cyclotron Plasma Heating and Current Drive at the L-2M Stellarator

Abstract— A quadrupole antenna has been designed and produced at the L-2M stellarator for experiments on ion cyclotron plasma heating current drive. Using a power meter of incident reflected waves, first measurements radiation resistance have performed in ohmic regime. The measured as function mean density. It is shown that fraction absorbed ensured by coaxial modes 25%. created can also be used proposed method based conversion fast magnetosonic waves to slow with their subsequent absorption electrons, which accompanied drive processes.
