2021年2月19日 · Our compact spherical tokamak, called ST40, is the latest step in our journey to deliver commercially viable fusion power and is expected to achieve fusion temperatures this year.

2024年4月16日 · In this article, we aim to show that the spherical tokamak (ST) device with high temperature superconducting (HTS) magnets could offer the quickest and lowest risk path to develop commercial fusion energy, which may be significantly advanced by the use of private–public partnerships.

2024年5月28日 · Spherical Tokamak: Pioneering Efficient Fusion Design. The quest for sustainable and clean energy sources has led scientists and engineers to explore nuclear fusion, where the Spherical Tokamak (ST) stands out for its …

A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants.

2024年8月9日 · Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), the private company Tokamak Energy, and Kyushu University in Japan have proposed a design for a compact, spherical fusion pilot plant that …

Our ST40 high-field compact spherical tokamak is the most advanced of its kind in the world. In 2022, we reached a world-record plasma ion temperature of 100 million degrees Celsius, the threshold for fusion energy.

The Spherical Torus/Tokamak (ST) is a low-aspect-ratio tokamak magnetic configuration characterized by strong intrinsic plasma shaping and enhanced stabilizing magnetic field line curvature. These unique ST characteristics enable the achievement of a high plasma pressure relative to the applied magnetic field

2024年5月28日 · At the heart of a Spherical Tokamak is the concept of magnetic confinement fusion. Unlike conventional tokamaks with a toroidal (doughnut-shaped) design, Spherical Tokamaks feature a more compact shape with a smaller aspect ratio—the ratio of the plasma major radius to the minor radius.

Our mission is to generate net energy from fusion and to stimulate an industry that will help prove its commercial viability. We’ll achieve this by producing a prototype tokamak powerplant – in an innovative spherical shape – to provide energy to the grid.

NSTX-U is the largest spherical tokamak in the U.S. and designed to be the most powerful of its kind in the world. Its sophisticated features enable scientists to test the viability of this compact design to reliably generate cost-effective electricity from fusion energy.
