Secondary Instability in Drift Wave Turbulence as a Mechanism for Avalanche Formation
نویسندگان
چکیده
We report on recent developments in the theory of secondary instability in drift-ITG turbulence. Specifically, we explore secondary instability as a mechanism for avalanche formation. A theory of radially extended streamer cell formation and self-regulation is presented. Aspects of streamer structure and dynamics are used to estimate the variance of the drift-wave induced flux. The relation between streamer cell structures and the avalanche concept is discussed, as are the implications of our results for transport modeling.

Secondary instability in drift wave turbulence as a mechanism for zonal flow and avalanche formation
The article reports on recent developments in the theory of secondary instability in drift–ion temperature gradient turbulence. Specifically, the article explores secondary instability as a mechanism for zonal flow generation, transport barrier dynamics and avalanche formation. These in turn are related to the space–time statistics of the drift wave induced flux, the scaling of transport with c...
متن کاملLaboratory studies of drift waves: Non-linear mode interaction and structure formation in turbulence
Coherent drift modes and drift wave turbulence is studied in a collisionality dominated high-density helicon plasma. The drift wave instability is identified by comparison of the drift mode density fluctuations characteristics with a linear dispersion relation, which reproduces the experimentally observed bent eigenmode structures due to radial gradients of the collisionality profile. Special a...

The generation of large-scale zonal flows by small-scale electrostatic drift waves in electron temperature gradient(ETG) driven turbulence model is considered. The generation mechanism is based on the modulational instability of a finite amplitude monochromatic drift wave. The threshold and growth rate of the instability as well as the optimal spatial scale of zonal flow are obtained.
متن کاملParticle acceleration in tangential discontinuities by lower hybrid waves
We consider the role that the lower-hybrid wave turbulence plays in providing the necessary resistivity at collisionless reconnection sights. The mechanism for generating the waves is considered to be the lower-hybrid drift instability. We find that the level of the wave amplitude is sufficient enough to heat and accelerate both electrons and ions.
