Intense geodesic acousticlike modes driven by suprathermal ions in a tokamak plasma.
Intense axisymmetric oscillations driven by suprathermal ions injected in the direction counter to the toroidal plasma current are observed in the DIII-D tokamak. The modes appear at nearly half theExpand

ALPHA-PARTICLE-DRIVEN TOROIDAL ALFVEN EIGENMODES IN THE TOKAMAK FUSION TEST REACTOR
Alpha-particle-driven toroidal Alfven eigenmodes (TAEs) have been observed for the first time in deuterium-tritium (D-T) plasmas on the tokamak fusion test reactor (TFTR). These modes are observedExpand

Active and fast particle driven Alfven eigenmodes in Alcator C-Mod
Alfven eigenmodes sAEsd are studied to assess their stability in high density reactor relevant regimes where Ti < Te and as a diagnostic tool. Stable AEs are excited with active magnetohydrodynamicsExpand

Beta-induced Alfvén-acoustic eigenmodes in National Spherical Torus Experiment and DIII-D driven by beam ions
Kinetic theory and experimental observations of a special class of energetic particle driven instabilities called here beta-induced Alfven-acoustic eigenmodes (BAAEs) are reported confirming,Expand

REVIEW ARTICLES Fusion plasma experiments on TFTR: A 20 year retrospective*
The Tokamak Fusion Test Reactor (TFTR) (R. J. Hawryluk, to be published in Rev. Mod. Phys.) experiments on high-temperature plasmas, that culminated in the study of deuterium–tritium D–T plasmasExpand

Correlation between electron transport and shear Alfvén activity in the National Spherical Torus Experiment.
We report the observation of a correlation between shear Alfvén eigenmode activity and electron transport in plasma regimes where the electron temperature gradient is flat, and thus the drive forExpand

Overview of physics results from MAST
Major developments on the Mega Amp Spherical Tokamak (MAST) have enabled important advances in support of ITER and the physics basis of a spherical tokamak (ST) based component test facility (CTF),Expand

Excitation of Alfvén cyclotron instability by charged fusion products in tokamaks
The spectrum of ion cyclotron emission (ICE) observed in tokamak experiments shows narrow peaks at multiples of the edge cyclotron frequency of background ions. A possible mechanism of ICE based onExpand

Predictions and observations of low-shear beta-induced shear Alfvén–acoustic eigenmodes in toroidal plasmas
New global MHD eigenmode solutions arising in gaps in the low frequency Alfven -acoustic continuum below the geodesic acoustic mode (GAM) frequency have been found numerically and have been used toExpand

On velocity space interrogation regions of fast-ion collective Thomson scattering at ITER
The collective Thomson scattering (CTS) diagnostic proposed for ITER is designed to measure projected 1D fast-ion velocity distribution functions at several spatial locations simultaneously. TheExpand
