Electron temperature effects in linear coupling of electron-cyclotron waves near the cut-off layers in fusion plasmas
Ordinary and extraordinary wave coupling in the electron-cyclotron frequency range in non-one-dimensionally inhomogeneous magnetized plasmas in a vicinity of the plasma cut-off surface is studied with taking into account electron thermal motion and tokamak magnetic field topology. Previously develop...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Ordinary and extraordinary wave coupling in the electron-cyclotron frequency range in non-one-dimensionally inhomogeneous magnetized plasmas in a vicinity of the plasma cut-off surface is studied with taking into account electron thermal motion and tokamak magnetic field topology. Previously developed theory of the ultra-highfrequency O-X mode coupling in a toroidal plasma has been generalized. Reduced wave equations that describe the normal wave interaction in the considered case are found and solved analytically. Thermal effects essential for the rf heating of overdense plasma in large scale experiment (ITER like) are analyzed. |
