Special behavior of alkali beam emission spectroscopy in low-ion-temperature plasma
P. Balázs, O. Asztalos, G. Anda +4
Beam emission spectroscopy (BES) is a powerful plasma diagnostic method especially suited for the measurement of plasma density and its fluctuations. As such, synthetic BES codes a…
On the interaction between the island divertor heat fluxes, the scrape-off layer radial electric field and the edge turbulence in Wendelstein 7-X plasmas
E. Maragkoudakis, D. Carralero, T. Estrada +11
The formation of the radial electric field, in the SOL has been experimentally studied for attached divertor conditions in stellarator W7-X. The main objective of this…
Identity of the JET M-mode and the ASDEX Upgrade I-phase phenomena
D. I. Réfy, E. R. Solano, N. Vianello +11
An H-mode plasma state free of edge-localized mode (ELM), close to the L-H transition with clear density and temperature pedestal has been observed both at the Joint European Torus…
Micro-Faraday cup matrix detector for ion beam measurements in fusion plasmas
Dániel Imre Réfy, Sándor Zoletnik, Dániel Dunai +9
Atomic Beam Probe (ABP) is an extension of the routinely used Beam Emission Spectroscopy (BES) diagnostic for plasma edge current fluctuation measurement at magnetically confined p…
Overview of recent physics results from MAST
A Kirk, J Adamek, RJ Akers +160
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…
On the effect of intermittency of turbulence on the parabolic relation between skewness and kurtosis in magnetized plasmas
Dávid Guszejnov, Attila Bencze, Sándor Zoletnik +1
This paper is aimed to contribute to the scientific discussions that have been triggered by the experimental observation of a quadratic relation between the kurtosis and skewness o…
Comparison of BES measurements of ion-scale turbulence with direct, gyrokinetic simulations of MAST L-mode plasmas
A R Field, D Dunai, Y-c Ghim +7
Observations of ion-scale (k_y*rho_i <= 1) density turbulence of relative amplitude dn_e/n_e <= 0.2% are available on the Mega Amp Spherical Tokamak (MAST) using a 2D (8 radial x 4…
Determination of structure tilting in magnetized plasmas - Time delay estimation in two dimensions
Dávid Guszejnov, Attila Bencze, Sándor Zoletnik +1
Time delay estimation (TDE) is a well-known technique to investigate poloidal flows in fusion plasmas. The present work is an extension of the earlier works of A. Bencze and S. Zol…
Three-dimensional modeling of beam emission spectroscopy measurements in fusion plasmas
D. Guszejnov, G. I. Pokol, I. Pusztai +4
One of the main diagnostic tools for measuring electron density profiles and the characteristics of long wavelength turbulent wave structures in fusion plasmas is Beam Emission Spe…
Experimental Signatures of Critically Balanced Turbulence in MAST
Y. -c. Ghim, A. A. Schekochihin, A. R. Field +8
Beam Emission Spectroscopy (BES) measurements of ion-scale density fluctuations in the MAST tokamak are used to show that the turbulence correlation time, the drift time associated…
Calculation of spatial response of 2D BES diagnostic on MAST
Y. -c. Ghim, A. R. Field, S. Zoletnik +1
The Beam Emission Spectroscopy (BES) turbulence diagnostic on MAST is to be upgraded in June 2010 from a 1D trial system to a 2D imaging system (8 radial \times 4 poloidal channels…
