摘要
The saturation analysis for the two-upper-hybrid-plasmon low-threshold parametric decay instability of the extraordinary wave is carried out for the conditions of the second harmonic ECRH experiments with due account of the daughter wave secondary decay and of the pump depletion. The anomalous absorption rate in the range of 10% is demonstrated for the parameters of the TEXTOR tokamak second harmonic X-mode ECRH experiment at a single-mode primary decay.
