Collisionless trapped electron mode in fluid and kinetic description

摘要

The effect of gyro-Landau drift resonances on the collisionless trapped electron mode have been studied. The drift resonances are added on a two-pole fluid model of the density response. The gyro-Landau drift resonances in general give good agreement with kinetic theory. Comparison is also made with the fluid model without drift resonances. Also the toroidal (eta)(sub i) mode is included in the system. (Atomindex citation 25:013204)
