Abstract

The antenna structure in the TCA tokamak is phased to preferentially excite Alfven waves with known toroidal and poloidal wavenumbers. Surprisingly the loading spectrum includes both discrete and continuum modes with poloidal wavenumbers incompatible with the antenna phasing. These additional modes, which are important for our heating experiments, can be attributed to linear mode coupling induced by the toroidicity of the plasma column, taking into account ion cyclotron effects.
