To create reliable, commercial nuclear fusion on Earth, scientists need to heat up plasma inside tokamak reactors to 150 million degrees Celsius—a temperature roughly 10 times that of the Sun’s core.

Chinese scientists have unveiled a superconducting linear plasma device designed to test materials for nuclear fusion reactors. The Superconducting Plasma Wall Interaction Linear Device (SWORD) boasts ...

Seeking to improve the tokamak fusion reactor known as ITER, researchers have found a way to stop rogue tungsten atoms from shearing off the walls and messing with the plasma. The finding is another ...

Fusion researchers are increasingly turning to the element tungsten when looking for an ideal material for components that will directly face the plasma inside fusion reactors known as tokamaks and ...

Japan’s JT-60SA fusion reactor project announced first plasma in October of this year to denote the successful upgrades to what is now the world’s largest operational, superconducting tokamak fusion ...

The massive, donut-shaped machine, which is also the largest and most powerful tokamak experiment, made headlines when it achieved 69 megajoules (MJ) of energy during a six-second pulse during its ...

Canadian startup General Fusion has been working on its unique approach to producing clean energy through nuclear fusion for two decades, and it's now got something major to show for it. The company ...

Encouraged by lab results and a feasibility study, Swedish startup, Green14, in collaboration with Sweden’s Royal Institute of Technology (KTH) plans to build a pilot-scale reactor to make solar grade ...

Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye. Plasma is an ionized gas -- that ...
