| Research Abstract |
Electron temperature gradient (ETG) perpendicular to magnetic field lines is formed by superimposing high-temperature electrons of an electron cyclotron resonance (ECR) plasma upon low-temperature thermionic electrons. The formed ETG is found to excite a high-frequency fluctuation (ETG mode), and also, to stimulate a low-frequency fluctuation (drift-wave mode) excitement via multi-scale nonlinear interaction, which ultimately causes ETG mode energy to be transferred to the drift-wave mode. Furthermore, the strong E×B velocity shear is demonstrated to suppress the ETG mode and drift-wave mode, experimentally.
