A team from Tokyo Metropolitan University developed a system to test magnetohydrodynamic aerobraking for spacecraft reentry. They successfully generated strong magnetic fields using an electromagnet, exceeding previous results with permanent magnets.
The papers validate and de-risk Commonwealth Fusion Systems' approach to commercial fusion, demonstrating scientifically robust path to grid electricity in the early 2030s. Advanced computational tools combined decades of empirical research on tokamaks worldwide, predicting 1.1 GW of fusion power and 400 MW of continuous net electricity.
Astronomers using astroseismology have found that massive stars' rotation rates decrease with age, but a new study suggests this may not be the case. The research team used 3D simulations to investigate how magnetic fields affect rotation inside massive stars, revealing that some configurations can spin the core up.
A global collaboration found that co-deposition is the dominant driver of fuel retention in lithium walls, and adding lithium during operation is more effective than pre-coating. The study offers insights into managing tritium, a rare fusion fuel, and improving plasma stability.
A new emulator model improves auroral current system simulations, enabling faster and more efficient space weather forecasts. The Surrogate Model for REPPU Auroral Ionosphere version 2 (SMRAI2) is a million times faster than physics-based simulations and incorporates seasonal effects.
A team of Japanese researchers discovered that adding neon to a hydrogen ice pellet can cool the plasma more effectively, reducing pressure and preventing ejection. This breakthrough contributes to establishing plasma control technologies for future fusion reactors.
The Princeton Plasma Physics Laboratory (PPPL) has received over $12 million in funding from the US Department of Energy to speed up the development of a pilot plant powered by fusion energy. This initiative aims to accelerate the production of clean and abundant electricity, a crucial step towards mitigating climate change.
Researchers at Princeton Plasma Physics Laboratory have successfully applied boron powder to tungsten components in tokamaks, improving plasma confinement and reducing the risk of edge-localized modes. The innovative approach uses a PPPL-developed powder dropper to deposit boron coatings while minimizing disruptions to the magnetic field.
