Trapped electron instabilities due to electron temperature gradient and anomalous transport

Abstract

The electrostatic trapped electron instabilities have been investigated by numerically solving the local single energy integral form dispersion relation. With the electron temperature gradient, the electron collision effect destabilizes the dissipative trapped electron mode (DTEM). For collisionless electrons, the energy dependent curvature drift effect strongly destabilizes the collisionless trapped electron mode. The growth rate is, however, reduced by a small collision effect. The anomalous transport due to these trapped electron modes is discussed. (author).
