Oxygen Formation in the Light of Gamma Beams
Department of Energy, Office of Science

Nuclear fusion reactions in stars consume carbon-12 to produce oxygen-16, and the resulting ratio of carbon to oxygen shapes a star’s evolution. Physicists have not been able to measure this ratio with precision using existing experimental methods. A new method shines gamma beams on an oxygen-16 target and captures images of the outgoing reaction products to obtain higher-quality data on this reaction.

For Plasma with a Hot Core and Cool Edges, Super-H Mode Shows Promise
Department of Energy, Office of Science

Fusion reactors face a challenge called “core-edge integration,” which involves maintaining a plasma that is hot at the core but not too hot to damage reactor walls. New research finds that a previously identified operating regime called Super H-mode can leverage the use of impurities such as nitrogen to address this challenge. The research also indicates that Super-H mode can be scaled up to future fusion plants.

Researchers Stick Out Their Necks to Understand How Fusion Plasmas Fuel Up

The nuclei that smash together to produce fusion energy in a reactor originate from ionized neutral particles. The edges of fusion devices have large numbers of neutrals available to gain or lose electrons to become ions. These neutrals influence several important features of the plasma, including the rate at which the plasma fuels a reactor. A new pinhole camera system called Lyman-alpha Measurement Apparatus (LLAMA) on the DIII-D tokamak helped researchers better understand these neutrals.

Taming the Plasma Edge: Reducing Instabilities in Tokamaks
Department of Energy, Office of Science

One of the challenges of fusion tokamaks is how to keep the core of a plasma hot enough that fusion can occur while preventing the tokamak walls from melting from that heat. This problem is even more difficult if instabilities at the plasma edge release energy in short bursts instead of a steady flow. Experiments on the DIII-D tokamak have demonstrated that enhancing energy flow in the plasma edge due to turbulent fluctuations can bleed energy smoothly out of the plasma, leading to improved future fusion plant efficiency.

Tokamak fusion reactors will generate huge amounts of heat that can damage reactor walls. Injecting impurities in the form of gases into the plasma can radiate away excess heat, but there is a limited range of gases that can be injected, and some gases react poorly with hydrogen fusion fuel. A new approach uses impurities in powder form, which allows researchers to introduce a considerable amount of material directly into the exhaust system for more efficient heat control.

Magnetic confinement fields in tokamaks can contain areas called magnetic islands in which plasma particles move extra quickly, preventing the plasma from reaching fusion temperatures. Researchers have now observed the spontaneous formation of a structure in the plasma with multiple magnetic islands. These “heteroclinic islands” do not merge into each other while embedded in a larger magnetic field tube. This information will aid the design and operation of future fusion reactors.
