Experimental data from many Tokamaks suggest that an important fraction of radial particle and heat transport in the Scrape-Off-Layer is due to poloidally-localized propagating structures of increased plasma density (blobs). A better understanding of the m ...
The acceleration of electrons during a sawtooth crash is demonstrated in various regimes of the TCV tokamak plasma. Simultaneous measurements of electron cyclotron emission from the low field side and from the high field side of the tokamak provide informa ...
The Tokamak `a Configuration Variable , TCV, addresses scientific questions to improve our understanding of magnetically confined plasmas and our ability to control them in ITER relevant scenarios, and explores avenues to improve the plasma performance on ...
The performance of tokamaks is usually described in terms of plasma temperature, density and confinement time. The term temperature implies that the plasma is in thermal equilibrium and its particles have maxwellian (normal) velocity distribution. However, ...
A core density fluctuation imaging diagnostic is being developed for the TCV tokamak, employing a 7 cm wide CO2 laser beam transmitted through the plasma in a near-toroidal direction. The proposed system employs the phase contrast method and can resolve wa ...
The development of controlled thermonuclear fusion, a quasi-unlimited energy source suitable for large scale electricity production, is one of the main goals of plasma physics research. Among the directions explored to date, the use of toroidal devices cal ...
Gyrokinetic calculations with the GS2 code of impurity transport in ASDEX Upgrade H-mode plasmas are presented. A method to separate the diagonal and off-diagonal terms in the quasi-linear flux computed by the gyrokinetic code for a trace impurity is intro ...
Almost since the first density profile measurements were made in the scrape-off layer (SOL) of the early tokamaks, it has been recognized that the rate of particle transport perpendicular to magnetic surfaces exceeds that expected on the basis of classical ...
Anomalous electron transport is determined by turbulence, which in turn is affected by magnetic shear. A novel application of electron cyclotron current drive (ECCD), aiming at localized shear modulation, has been applied on the TCV tokamak for experiments ...
The role of the current profile and ion and electron temperature ratio in Tokamak A Configuration Variable (TCV) electron internal transport barrier (eITB) noninductive discharges is inspected by means of the linear gyrokinetic global code LORB5 (Bottino e ...
