Abstract

Finite-γ (plasma pressure/magnetic pressure) and resonant electron effects on the dissipative trapped-electron instabilities are analysed. These modifications are shown to have a strong stabilizing influence on the finite-ion-gyroradiusand electron-temperature-gradient-driven modes, respectively. For relevant tokamak parameters, complete stabilization may be possible. Stability criteria for radially local and non-local cases are presented.
