Anomalous slowing of lower hybrid waves in toroidal plasma
Baranov Yu. F. , Piliya A. D. , Esterkin A. R.
Waves in the frequency range ^%e6)Hi < ω < 6>He can undergo an anomalous slowing in a toroidal tokamak plasma. In the approximation of a cold plasma, there exists a ray-trajectory attractor. As this attractor is approached, the wave vector к and the wave field Ε increase without bound. An effective Cerenkov absorption of rf power occurs in a plasma with a nonzero temperature.
