Tokamak Energy is a fusion power company based near Oxford in the United Kingdom, [1] established in 2009. [2] The company is pursuing the global deployment of commercial fusion energy in the 2030s through the combined development of spherical tokamaks with high-temperature superconducting (HTS) magnets. It is also developing HTS magnet ...
A spherical tokamak is a type of fusion power device based on the tokamak principle. It is notable for its very narrow profile, or aspect ratio. A traditional tokamak has a toroidal confinement area that gives it an overall shape similar to a donut, complete with a large hole in the middle. The spherical tokamak reduces the size of the hole as ...
Spherical Tokamak for Energy Production (STEP) is a spherical tokamak fusion plant concept proposed by the United Kingdom Atomic Energy Authority (UKAEA) and funded by the UK government. [ 1 ] [ 2 ] [ 3 ] The project is a proposed DEMO -class successor device to the ITER tokamak proof-of-concept of a fusion plant, the most advanced tokamak ...

The Culham Centre for Fusion Energy (CCFE) is the UK's national laboratory for fusion research.It is located at the Culham Science Centre, near Culham, Oxfordshire, and is the site of the Mega Ampere Spherical Tokamak (MAST) and the now closed Joint European Torus (JET) and Small Tight Aspect Ratio Tokamak (START).
2015: ST25-HTS at Tokamak Energy Ltd in Culham, United Kingdom; 2017: KTM – this is an experimental thermonuclear facility for research and testing of materials under energy load conditions close to ITER and future energy fusion reactors, Kazakhstan; 2018: ST40 at Tokamak Energy Ltd in Oxford, United Kingdom
The 3 October 2019 UK Atomic Energy announcement of its Spherical Tokamak for Energy Production (STEP) [18] grid-connected reactor for 2040 suggests a combined DEMO/PROTO phase machine apparently to be designed to leapfrog the ITER timetable. [19] China's proposed CFETR machine, a grid-connected gigawatt-generating reactor, overlaps the DEMO ...
In 1999, the National Spherical Torus Experiment (NSTX), based on the spherical tokamak concept, came online at the PPPL. Odd-parity heating was demonstrated in the 4 cm radius PFRC-1 experiment in 2006. PFRC-2 has a plasma radius of 8 cm. Studies of electron heating in PFRC-2 reached 500 eV with pulse lengths of 300 ms. [10]
