N2 - 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 emitted from a tungsten hot plate. The formed ETG is found to excite a high-frequency fluctuation, i.e., ETG mode, and also, to enhance a low-frequency fluctuation originally caused by an ExB velocity shear. Furthermore, the strong ExB velocity shear is demonstrated to suppress the ETG mode experimentally.
