概要
- 論文の詳細を見る
A collisional drift wave localized about a mode rational surface is discussed in a slab model by means of a model equation for the electrostatic potential comprising the usual nonlinear term due to the polarization drift and a collisional effect enhanced by a magnetic shear. Also an ion-acoustic wave propagating in the poloidal direction with the toroidal symmetry is studied to examine a possibility that solitons with scale of the effective ion-Larmor radius are formed. A kdv equation is derived for a plasma rotating with a speed nearly equal to the wave velocity.
