Non-resonant parametric decay of lower-hybrid waves in the ACT-1 toroidal device

Technical Report ·
DOI:https://doi.org/10.2172/6593917· OSTI ID:6593917
;
Non-resonant parametric decay of lower-hybrid waves, observed in a number of high-power tokamak rf heating experiments, is positively identified as a decay into ion-cyclotron quasi-modes. The decay-wave spectrum, wavelength and amplitude profile are measured inside a toroidal plasma with pump frequency f/sub 0/ approx. 3.5 f/sub ..pi../ approx. 25 f/sub ci/.
