Multiscale Modelling for Tokamak Pedestals

, 2018
Pedestal modelling is crucial to predict the performance of future fusion devices. Current modelling efforts suffer either from a lack of kinetic physics, or an excess of computational complexity.

Continuous tokamaks [PDF]

, 1978
A tokamak configuration is proposed that permits the rapid replacement of a plasma discharge in a ''burn'' chamber by another one in a time scale much shorter than the elementary thermal time constant of the chamber first wall. With respect to the chamber, the effective duty cycle factor can thus be made arbitrarily close to unity minimizing the cyclic

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.

Effective Resistivity for Magnetohydrodynamic Simulation of Collisionless Magnetic Reconnection

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract The electron inertia and the off‐diagonal electron pressure terms are well‐known for the frozen‐in condition breakdown in collisionless magnetic reconnection, which are naturally kinetic and difficult to employ in magnetohydrodynamic (MHD) simulations.

A h‐Adaptivity Strategy for Hybridizable Discontinuous Galerkin (HDG) Simulations of Fluid Transport Models in Tokamak Plasma

International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.
ABSTRACT The highly anisotropic, multi‐scale nature of fusion plasma simulations in tokamaks, combined with the complexity in the geometries of plasma‐facing components and magnetic equilibrium, challenges numerical schemes. They therefore require the development of advanced numerical techniques to enhance computational efficiency and enable codes to ...

Measurements of Auroral Plasma Properties Using Low‐Cost, Mobile, Ground‐Based Detectors

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract An expedition to Fairbanks, AK, was undertaken to study the aurora during the peak of solar cycle 25. Low‐cost diagnostics were developed to enable ground‐based measurements of ionospheric plasma parameters and auroral phenomena, namely a compact spectrometer and a high‐resolution all‐sky camera with 2‐axis magnetometer. Observations were made

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Cross-tokamak disruption prediction based on domain adaptation

Nuclear Fusion
The high acquisition cost and the significant demand for disruptive discharges for data-driven disruption prediction models in future tokamaks pose an inherent contradiction in disruption prediction research.
