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

Runaway electron mitigation by 3D fields application in ASDEX Upgrade, COMPASS, and RFX-mod

Frontiers in Physics
Disruption-generated runaway electron (RE) beams represent a potentially severe threat for tokamak plasma-facing components. Application of properly designed 3D fields can act as a mitigation mechanism, as recently investigated in ASDEX Upgrade (AUG) and

Long plasma duration operation analyses with an international multi-machine (tokamaks and stellarators) database

Nuclear Fusion, 2023
Combined high-fusion performance and long-pulse operation is one of the key integration challenges for fusion energy development in magnetic devices. Addressing these challenges requires an integrated vision of physics and engineering aspects with the ...

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 ...

Evidences for and the models of self-similar skeletal structures in fusion devices, severe weather phenomena and space [PDF]

, 2005
The paper briefly reviews (i) the evidences for self-similar structures of a skeletal form (namely, tubules and cartwheels, and their simplest combinations), called the Universal Skeletal Structures (USS), observed in the range 10-5 cm - 1023 cm.

Diagnostic systems in DEMO: engineering design issues

, 2014
The diagnostic systems of DEMO that are mounted on or near the torus, whether intended for the monitoring and control functions of the engineering aspects or the physics behaviour of the machine, will have to be designed to suit the hostile nuclear ...

Fast and Invertible Simplicial Approximation of Magnetic‐Following Interpolation for Visualizing Fusion Plasma Simulation Data

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Numerical methods for the magneto-mechanical coupling analysis of in-vessel components in Tokamak devices

Theoretical and Applied Mechanics Letters, 2019
: Magneto-mechanical coupling vibration arises in the in-vessel components of Tokamak devices especially during the plasma disruption. Strong electromagnetic forces cause the structures to vibrate while the motion in turn changes the distribution of the ...
