Zonal flow generation in collisionless trapped electron mode turbulence

J Anderson, H Nordman, R Singh, J Weiland2006年Plasma Physics and Controlled FusionIF 2.2出版社

In the present work the generation of zonal flows in collisionless trapped electron mode (TEM) turbulence is studied analytically. A reduced model for TEM turbulence is utilized based on an advanced fluid model for reactive drift waves. An analytical expression for the zonal flow growth rate is derived and compared with the linear TEM growth, and its scaling with plasma parameters is examined for typical tokamak parameter values.
