Scientists in China have made a new system for fueling the tokamak device. The continuous cryogenic pellet injection system overcomes challenges related to cryogenic ice formation and many others.

As the Sun and stars themselves can attest, nuclear fusion could be an essentially unlimited energy source, if we can only harness it. The problem is that the plasma used is inherently unstable, and ...

ITER’s success will depend in part on subduing potential plasma instabilities. This ORNL team is tackling the challenge with shattered pellet injection. A team of experts at Oak Ridge National ...

R&D engineer and pellet injection scientist Trey Gebhart of the Blanket and Fuel Cycle group in ORNL’s Fusion Energy Division with a pellet injection system testbed used for fusion R&D. The group ...

Researchers have 'chilled out' unwanted hot spots inside a plasma fusion vessel by injecting pellets of frozen neon and deuterium straight into the hot plasma. A shot of icy chemical cocktail -- ...

Injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performance. Studies by physicists compared the two methods on the DIII-D National Fusion Facility, looking ahead to ...
