Notes:
The effects of collisions and anisotropy in the ion temperature gradient on the ion-temperature-gradient-driven (ITG) mode are investigated with dissipative trapped electrons and fully kinetic ions, in the presence of both transit and magnetic drift resonances. For the slab and toroidal modes, electron collisions stabilize the ion branch but destabilize the electron branch. For the mixed slab and toroidal mode, a coupling effect is found that causes a split of the stability region in the ηi(parallel)-ηi⊥ plane. A second stability region at large ηi⊥ with electron collisions may provide a possible stabilization scheme for ITG instabilities.
