Analysis of Tokamak fusion device parameters affecting the efficiency of Tokamak operation
PAM Review Energy Science & Technology, 2017 Nuclear Power has been available as a relatively clean and reliable energy source for several decades. While tokamak engines have been in existence almost as long as successful fission-powered nuclear generators, they have not yet reached operational success for energy generation.

2D continuous spectrum of shear Alfven waves in the presence of a magnetic island
, 2010 The radial structure of the continuous spectrum of shear Alfven modes is calculated in the presence of a magnetic island in tokamak plasmas. Modes with the same helicity of the magnetic island are considered in a slab model approximation.

Entropy, 2019 In studying the hot plasma behavior in tokamak devices, the classical approach for collisional processes is traditionally used. This approach leaves unexplained a number of phenomena observed in experiments related to plasma energy confinement.

Methods for characterising microphysical processes in plasmas [PDF]
, 2013 Advanced spectral and statistical data analysis techniques have greatly contributed to shaping our understanding of microphysical processes in plasmas. We review some of the main techniques that allow for characterising fluctuation phenomena in geospace ...

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.
