Tokamak Energy’s pre-concept design for a fusion power plant: an overview of ST-E1

Nuclear Fusion
Climate change and rapidly rising energy demand, driven in part by artificial intelligence and data-centre growth, create an urgent need for stable, low-carbon, and abundant power. Fusion is a promising long-term solution, yet its commercialisation faces

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.

Power and particle exhaust in the ST-E1 fusion power plant

Nuclear Fusion
Power exhaust challenges and potential solutions for a 5 m major radius, low-aspect ratio burning tokamak have been explored. 1D edge plasma models have been used to screen for access to detachment using short and long outer divertor legs in double and ...

Practical Model for the Calculation of Lateral Electromagnetic Loads in Tokamaks at Asymmetric Vertical Displacement Events (AVDEs)

Plasma
This paper describes a new practical numerical model for the calculation of lateral electromagnetic (EM) loads in tokamaks during asymmetric vertical displacement events (AVDEs). The model combines key features of two recently reported trial models while

Theoretical relation between halo current-plasma energy displacement/deformation in EAST

Journal of Theoretical and Applied Physics, 2018
In this paper, theoretical model for calculating halo current has been developed. This work attained novelty as no theoretical calculations for halo current has been reported so far. This is the first time to use theoretical approach.
