Spherical Tokamak

Just two weeks since raising $125mn in funding, British scaleup Tokamak Energy has secured backing from the US and UK to upgrade its ST40 fusion energy plant. The US Department of ...

The unimaginably complex task of creating, containing, and commercialising fusion energy is undoubtedly one of the greatest scientific endeavours of our time. Since the 1950s, ...

The ST40, a compact high-field spherical tokamak, has achieved ion temperatures more than 5 keV—a feat not attained previously.

The paradox startled scientists at the U.S Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) more than a dozen years ago. The more heat they beamed into a spherical tokamak, a magnetic facility designed to reproduce the fusion energy that powers the sun and stars, the less the central temperature increased.

To produce commercial energy, future fusion power plants will need to achieve temperatures of 100 million degrees C. To do so requires careful control of the plasma. In a study published in the journal Nuclear Fusion, researchers refined operating conditions to achieve the necessary temperatures in a compact spherical tokamak device called ST40.

Two identical remotely-operated manipulators used to maintain the Joint European Torus fusion energy machine at the Culham Science Centre in Oxfordshire, UK, are being tested in a series of practice 'rescue missions', where each saves its stranded twin.

British scaleup Tokamak Energy has secured $125mn as it looks to harness fusion — the same clean, virtually limitless energy source that powers the Sun and stars. Tokamak spun ...

While the tech downturn rumbles on, investment in nuclear fusion remains strong — in 2021, over €2.7 billion was injected in this field alone. More recently, the UK Space Agency ...

The Japanese tech firm can now enhance its nuclear fusion reactor development.

Supercooled rare-earth barium copper oxide could be the magic ingredient that lets humanity finally make a successful fusion engine.

British startup Tokamak Energy is testing a new type of laser that it says is "crucial" to stabilising fusion reactions — the same atom-fusing process that powers the Sun and ...

Since Brexit, the UK no longer has access to ITER, the world's largest nuclear fusion experiment, through the European Union. After an invitation to rejoin this week, the UK government has confirmed it prefers to go it alone

In its last hurrah before being shut down, a 40-year-old fusion reactor in the UK set a new world record for energy output — bringing the decades-old promise of clean, limitless energy ...

Letters to the editors for the July/August 2023 issue of Scientific American

The UK's dream of having the world's first commercial nuclear fusion power plant has taken a digital turn. As part of plans to put fusion energy on the grid by 2040, a digital twin ...

Working with Intel technology in the industrial metaverse, engineers in the UK develop next-generation power production for the future.

The National Spherical Torus Experiment-Upgrade (NSTX-U) could serve as the model for a fusion energy pilot plant.

Doing something for the first time is tough. Yet to replicate the nuclear fusion process that powers the very stars, and do it right here on Earth in a controlled and sustained fashion is decidedly at...
