Drift waves occur universally in magnetized plasmas producing the dominant mechanism for
the transport of particles, energy and momentum across magnetic field lines. A wealth of …

This review covers the group of data-analysis techniques collectively referred to as
symbolization or symbolic time-series analysis. Symbolization involves transformation of raw …

Turbulence in tokamaks is characterized by long parallel wavelengths and short
perpendicular wavelengths. A coordinate system for nonlinear fluid, gyrokinetic ''Vlasov,''or …

The present status of zonal flow experiments is reviewed with the historical process to attain
the concept of zonal flows, which provides a new framework for understanding turbulence …

Doppler reflectometry is characterized by a finite tilt angle of the probing microwave beam
with respect to the normal onto the cutoff surface. According to the Bragg condition the …

A recently introduced tool for the analysis of turbulence, wavelet bicoherence [van Milligen,
Hidalgo, and Sanchez, Phys. Rev. Lett. 16, 395 (1995)], is investigated. It is capable of …

This paper presents a pedagogical review of the physics of mesoscopic transport events and
their role in the breakdown of Fick's Law for turbulent transport in magnetically confined …

This article is about microwave reflectometry—a radar technique for plasma density
measurements using the reflection of electromagnetic waves by a plasma cutoff. Both the …

Transport is the outstanding physics issue in the quest for fusion by magnetic confinement.
In spite of the intrinsic difficulty, a great deal of progress has been made in the past 25 years …

Peak fusion power production of 6.2±0.4 MW has been achieved in TFTR plasmas heated
by deuterium and tritium neutral beams at a total power of 29.5 MW. These plasmas have an …
