, 2020 We study the effect of turbulent transport in different magnetic configurations of the Weldenstein 7-X stellarator. In particular, we performed direct numerical simulations with the global gyrokinetic code GENE-3D, modeling the behavior of Ion ...

The Riddle of Ball Lightning: A Review
The Scientific World Journal, Volume 6, Issue 1, Page 254-278, 2006., 2006 One of the most intriguing and enduring scientific challenges is to find an explanation for ball lightning, the shining fireballs that sometimes appear near lightning strokes. Although many theoretical ideas have been proposed and much experimental work has been performed, there is not yet an accepted explanation of their amazing properties.

On neoclassical impurity transport in stellarator geometry
, 2013 The impurity dynamics in stellarators has become an issue of moderate concern due to the inherent tendency of the impurities to accumulate in the core when the neoclassical ambipolar radial electric field points radially inwards (ion root regime).

Discrete Dynamics in Nature and Society, Volume 3, Issue 4, Page 251-266, 1999., 1999 Three kinds of results have been described in this paper. Firstly, an experimental study of the Rossby vortex meridional drift on the rotating shallow water has been carried out. Owing to the stringent physical analogy between the Rossby vortices and drift vortices in the magnetized plasma, the results obtained have allowed one to make a conclusion ...

Global magnetofluidostatic fields (an unsolved PDE problem)
International Journal of Mathematics and Mathematical Sciences, Volume 9, Issue 1, Page 123-130, 1986., 1986 A satisfactory theory of the Global MagnetoFluidoStatic (GMFS) Fields, where symmetric and non‐symmetric configurations can be dealt with on the same footing, has not yet been developed. However the formulation of the Nowhere‐Force‐Free, Local‐Global MFS problem about a given smooth isobaric toroidal surface 𝒮0 (actually, a degenerate initial‐value ...

Global Alfven Eigenmodes in the H-1 heliac [PDF]
, 2017 Recent upgrades in H-1 power supplies have enabled the operation of the H-1 experiment at higher heating powers than previously attainable. A heating power scan in mixed hydrogen/helium plasmas reveals a change in mode activity with increasing heating ...

Methods for Color Center Preserving Hydrogen‐Termination of Diamond
Advanced Materials Interfaces, Volume 11, Issue 24, August 23, 2024.Hydrogen‐termination of diamond by three methods. Hydrogen plasma exposure with stage heating above 700 °C yields maximal coverage but causes irr loss of shallow nitrogen‐vacancy fluorescence. Plasma exposure without heating preserves nitrogen‐vacancies at the expense of increased oxygen coverage.

Impurities in a non-axisymmetric plasma: transport and effect on bootstrap current [PDF]
, 2015 Impurities cause radiation losses and plasma dilution, and in stellarator plasmas the neoclassical ambipolar radial electric field is often unfavorable for avoiding strong impurity peaking.

Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.Abstract The distribution pattern of the connection length in the divertor region of Heliotron J was calculated by the field line tracing method. A multifold layer structure, characterized by the range of connection length, was revealed to interpret the response of the transport of the lower‐charged impurity ions to the divertor structure.
