Neutral beam driven ion cyclotron instability of lower hybrid wave in a tokamak plasma
AIP Advances, 2022 The effect of dust grains on the parametric coupling of neutral beam driven ion–cyclotron wave instability with a lower hybrid pump wave is studied. A high amplitude lower hybrid pump, which is launched into a tokamak for heating purposes in the presence

A Drift-Kinetic Analytical Model for SOL Plasma Dynamics at Arbitrary Collisionality [PDF]
, 2017 A drift-kinetic model to describe the plasma dynamics in the scrape-off layer region of tokamak devices at arbitrary collisionality is derived. Our formulation is based on a gyroaveraged Lagrangian description of the charged particle motion, and the ...

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion
International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1541-1557, December 2025.Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

Kinetic modelling of runaway electron avalanches in tokamak plasmas
, 2015 Runaway electrons (REs) can be generated in tokamak plasmas if the accelerating force from the toroidal electric field exceeds the collisional drag force due to Coulomb collisions with the background plasma.

Excitation of Whistler‐Mode Waves by an Electron Temperature Anisotropy in a Laboratory Plasma
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Naturally occurring whistler‐mode waves in near‐Earth space play a crucial role in accelerating electrons to relativistic energies and scattering them in pitch angle, driving their precipitation into Earth's atmosphere. Here, we report on the results of a controlled laboratory experiment focusing on the excitation of whistler waves via ...

The Solar Wind Interaction With an Orbiting Venus
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Studies of the large‐scale interaction of the solar wind with planets have often been considered along the line of the sun to the planet, neglecting the planet's orbital motion. This paper describes a new refinement in the long history of Venus simulations, the addition of the planet's orbital motion.

Tungsten melting and erosion under plasma heat load in tokamak discharges with disruptions
Nuclear Materials and Energy, 2017 Full tungsten poloidal and mushroom limiters were tested in series of experiments with disruptions in the T-10 tokamak. Significant melting, formation of small craters and erosion of the tungsten limiter have been observed after ∼400 discharges with ...
