Experimental investigation of nonlinear interactions of drift waves
… is high enough. This wave and the ordinary drift wave interact nonlinearly to produce new waves at the sum and difference frequencies. The amplitude of the wave at the difference frequency is an order of magnitude smaller than that of the primary waves which have the same order of magnitude …

Theoretical transport model for tokamaks
… linear combination of two transport mechanisms; drift waves, which dominate the transport in the core region, and resistive ballooning modes, which dominate the transport in the edge region. The resulting unified model has been used in a predictive transport code to simulate the plasma transport …

Methods for Testing Transport Theories
… of several theoretical transport fluxes, namely, drift waves, resistive ballooning, and rippling modes added to a fixed level of neoclassical transport. The purpose of this work is to calibrate the proposed model against existing L-mode energy confinement time data.

Fluctuation induced cross-field transport in Hall thrusters and tokamaks
… Hall thrusters, both have magnetized electrons, drift waves occur in both regimes and many of the observed fluctuations are of similar scale. Generally, research on cross-field transport within the tokamak community is isolated from work done within the thruster community. However, analysis of …

Understanding the Mechanisms that Determine the Edge Electron Density Profile in Tokamaks
… instabilities as opposed to that resulting from drift-waves. Reaching the threshold in this parameter may be avoided through improved particle control and is found to also be highly dependent on the 2D distribution of neutrals in the unconfined plasma region. The competition between interchange …

A study on the ion temperature gradient driven turbulence in tokamak plasmas
… by the destabilization of low frequency drift wave fluctuations, resulting in turbulence in the plasma on small scales compared to the tokamak size. The drift waves are collective modes of plasma oscillations that propagate through the plasma, arising as a result of the independent …
