The ECE diagnostic at W7-X in its standard mode of operation measures in X2 mode polarization with a 32 channel radiometer in the frequency band around 140 GHz for central magnetic field 2.5T. The radiometer is calibrated by a noise source and the ov

A 3-dimensional Particle-Particle Particle-Mesh (P3M) code is applied to study the charging process of micrometer size dust grains confined in a capacitive RF discharge. In our model, particles (electrons and ions) are treated kinetically (Particle-i

The entropy properties in a D.C. argon arc plasma source are studied. The local thermodynamical entropy relations are established for a set of uniform sub-systems (Ar, A+, e) in order to deduce the entropy balance equation in presence of dissipative

The steady state operation of Wendelstein 7-X stellarator presently under construction in Greifswald poses special challenges to the diagnostics development [1, 2]. A critical issue is the heat load on plasma facing components (∼500 kW/m2) over a l

The heavy ion beam probe (HIBP) is an established non perturbing diagnostic for measuring the spatial distributions of plasma potential, density, temperature and poloidal magnetic field (axial current) of magnetically confined fusion plasma. These ar

The video diagnostics for W7-X—which is under development—is devoted to observe plasma and frrst wall elements during operation, to warn in case of hot spots and dangerous heat load and to give information about the plasma size, position, edge st

An analytical solution to the question of transversal displacement of plasma beam moving in a toroidal magnetic field is proposed. The equations describing the transversal motion of ions and electrons have been made self-consistent using some results

Poloidal E×B shear flows are widely accepted as a trigger mechanism of transport barriers in the edge of fusion plasmas. Strong E×B flows can act on turbulence and turbulent transport through the shear decorrelation mechanism, which can reduce the
