A renovated, second-generation fusion reactor in England has achieved first plasma. This reactor and other fusion reactors have long-shot plans to produce energy as early as 2040. The new reactor ...

Hot stuff: The first plasma has been recorded at the upgraded Mega Amp Spherical Tokamak. (Courtesy: Culham Centre for Fusion Energy) Officials at the Culham Centre for Fusion Energy (CCFE) in ...

The prospect of commercially viable, fusion-power plants based on the spherical tokamak has moved closer after a major experiment in the UK released its first results. Using a novel kind of exhaust, ...

The UK Atomic Energy Authority's fusion energy experiment - the Mega Amp Spherical Tokamak (MAST) Upgrade tokamak at Culham Science Centre - has achieved first plasma for the first time. MAST Upgrade ...

The UK Atomic Energy Authority and Tokamak Energy have signed a five-year framework agreement for closer collaboration "on developing spherical tokamaks as a route to commercial fusion energy". The ...

Among the top puzzles in the development of fusion energy is the best shape for the magnetic facility -- or "bottle" -- that will provide the next steps in the development of fusion reactors. Leading ...

As the race towards the first commercially viable nuclear fusion reactor heats up, the UK-based Tokamak Energy has published a paper on its recent achievements with its ST40 spherical tokamak. Most ...
