Abstract
The intensity ratio of the second- to the third-harmonic cyclotron emission, measured by a scanning Fourier-transform spectrometer, is investigated for a wide range of discharge parameters. Dependences of the ratio on electron temperature and density are described by the model of plane-parallel walls. The time evolution of central electron density deduced from the ratio is consistent with multichannel interferometer data within the estimated experimental error.
