Abstract
The scenario of low-threshold decay of an ordinary microwave with a frequency corresponding to the second harmonic of electron cyclotron resonance, leading to the excitation of two electron Bernstein waves two- dimensionally localized in a large-scale coherent structure in a rarefied plasma, has been investigated. Using the proposed model, estimates for the threshold of this nonlinear phenomenon were obtained for ASDEX-Upgrade and Wendelstein 7-X facilities, as well as in a model experiment on a linear device.
