Investigation of Electron Heating Due to the Kinetic Shear Alfven Wave in the Toroidal Plasma

Abstract

Shear Alfven wave heating experiments are reported in which a bulk electron heating of the toroidal plasma for a high initial temperature plasma (T_e>50 eV) and a local electron heating for a lower temperature plasma were observed. The results indicate the excitation of the kinetic shear Alfven wave and are consistent with the theoretical calculation of the damping length of the wave.
