Fusion reactor that employs liquid metal shower

In a magnetic field confinement fusion reactor, we maintain the high-temperature plasma through the magnetic field lines by floating the plasma apart from a vessel. However, there forms inevitably a location where the plasma ...

EAST achieves longest steady-state H-mode operations

Celebrating the 10th anniversary of physics operations, the 11th EAST (Experimental Advanced Superconducting Tokamak) campaign reached a milestone in the exploration of advanced operation scenarios—achieving over 60s fully ...

Tritium introduced in fusion experiments at Sandia

Researchers at Sandia National Laboratories Z Machine have opened a new chapter in their 20-year journey toward higher fusion outputs by introducing tritium, the most neutron-laden isotope of hydrogen, to their targets' fuel.

Fusion reactor designs with 'long legs' show promise

Magnetic fusion is all about managing the interface between hot plasma and ordinary materials. The strong magnetic field in a tokamak—the vessel used in this fusion approach—is a very effective insulator; it is able to ...

Fixing deficits in boundary plasma models

Researchers working on the DIII-D tokamak in San Diego are working to show how plasma transport and atomic physics come together to provide power exhaust solutions.

From Germany comes a new twist for fusion research

This past year saw the commissioning and initial operation of a new large-scale plasma experiment, the Wendelstein 7-X (W7-X) in Greifswald, Germany. Designed, constructed, and operated by the Max-Planck Institute for Plasma ...

A turbulent solution to a growing problem

A recent experiment lead by University of California, Los Angeles (UCLA), researchers on the DIII-D tokamak suggests that plasma turbulence can prevent filamentary structures called magnetic islands from growing so large ...

Steering a fusion plasma toward stability

Plasmas in fusion-energy producing devices are gases heated to millions of degrees that can carry millions of amperes of current. These superhot plasmas must be kept away from material surfaces of the vacuum vessel that contains ...

Alcator C-mod bows out with a new world record

On its final day of operation, the Alcator C-Mod tokamak at the Massachusetts Institute of Technology's Plasma Science & Fusion Center set a new record for plasma pressure in a magnetic confinement device. These results help ...

Extinguishing a fusion fire in a flash of light

Fusion energy researchers have discovered that they can rapidly extinguish and cool a magnetically confined fusion plasma hotter than the center of the sun by injecting a large quantity of neon gas to prevent damage to fusion-energy ...
