The generation of zonal flows and zonal fields by finite Î² drift waves in plasmas with finite ion temperature Ti is investigated. This work extends our earlier work with zero ion temperature. The growth rate of the zonal flow and field is enhanced by finite Ti effects. This leads to a...

A one-dimensional transport model is developed to simulate the confinement of plasma and magnetic flux in a field-reversed configuration. Given the resistivity, the confinement times can be calculated. Approximate expressions are found which yield the magnitude and gross profile of the...

It is shown here that microturbulence can be stabilized in the presence of steep temperature and density profiles. Indeed in high Î² plasmas, pressure profile gradients are associated with high &varbarÎ²â€²&varbar; = Î´Î²/Î´Ï, where Î²=P/(B[SUP2]/2Î¼[SUB0]) and Ï the...

Turbulent drift-wave dynamics in a sheared magnetic field are studied using direct numerical simulations. Self-consistent nonadiabatic electron and parallel ion dynamics are both retained in a 2-D sheared-slab model. Magnetic shear causes division of the system into two physically distinct...

A kinetic theory of collisionless and dissipative trapped-electron-driven drift wave turbulence in a sheared magnetic field is presented. Weak turbulence theory is employed to calculate the nonlinear electron and ion responses and to derive a wave kinetic equation that determines the nonlinear...

The spatiotemporal multiscale dynamics of the turbulent transport of impurities is studied in the context of the collisional drift wave turbulence. Two turbulence regimes are considered: a quasihydrodynamic regime and a quasiadiabatic regime. The impurity is assumed to be a passive scalar...

Zonal flows, which means azimuthally symmetric band-like shear flows, are ubiquitous phenomena in nature and the laboratory. It is now widely recognized that zonal flows are a key constituent in virtually all cases and regimes of drift wave turbulence, indeed, so much so that this classic...

A convexity argument is used to show that an equilibrium in the nonlinear stability of cold electron plasma must be axisymmetric. (AIP)

The stability of axisymmetric tandem mirror plasmas with respect to interchange, rotational, and ballooning modes is investigated in the paraxial approximation. The stabilizing effects of finite orbits, rigid energetic fast-drifting electrons, nearby conducting walls, and line-tying by a cold...
