The overview discusses development of the unique fusion plasma diagnostics—Heavy Ion
Beam Probing (HIBP) in application to toroidal magnetic plasma devices. The basis of the …

Zonal flows and their high-frequency counterpart, the geodesic acoustic modes (GAMs) are
considered as a possible mechanism of the plasma turbulence self-regulation. In the T-10 …

New findings in study of geodesic acoustic modes (GAMs) on the T-10 tokamak since the
last IAEA FEC 2014 are described. The broadband fluctuations of potential φ and electron …

Electric field Ε or electric potential φ plays a key role in the transport and turbulence of
toroidal plasmas. It is believed that mean radial E r suppresses the turbulence eddies via E× …

Axisymmetric geodesic acoustic mode (GAM) oscillations of the magnetic field, plasma
potential and electron temperature have been identified on the COMPASS tokamak. This …

For low-frequency kHz) plasma electric potential oscillations, measured in two toroidally
spaced vertical cross sections of the TJ-II stellarator (m, m, T) using double heavy ion beam …

A new kind of quasi-coherent mode was observed in ohmic plasma in the STOR-M tokamak.
It is featured with a clear solitary peak around 30–35 kHz in the power spectra of the ion …

The geodesic acoustic mode (GAM) has been observed for the first time in EAST H-mode
operation using Doppler backscattering (DBS) systems. The poloidal and toroidal …

Для низкочастотных (0< f< 20 кГц) колебаний электрического потенциала плазмы,
измеренных в двух тороидально разнесенных вертикальных сечениях стелларатора …

Joint experiments (JEs) on small tokamaks have been regularly performed between 2005
and 2015 under the framework of the International Atomic Energy Agency (IAEA) …
