Abstract

The linear electron temperature gradient (EGR) mode spatial structure was studied in the presence of nonuniform toroidal and poloidal plasma flow.It was observed that the growth rate of the ETG mode does not changed by flow shear. But it was found that the spatial structure of the ETG mode depended on the derivative of the flow shear rate with respect to the minor radius of the tokamak cross section and also on the magnetic shear. The results showed that the small radial extent of these modes may reduce electron heat transport, which would enhance the formation of an electron thermal transport barrier.
