TRIUMF Theory Helps Shed New Light on Thermonuclear Fusion of Deuterium and Tritium

TRIUMF

Scientists at TRIUMF, the Institut de Physique Nucléaire, and Lawrence Livermore National Laboratory have for the first time accurately predicted the properties of polarized deuterium-tritium thermonuclear fusion. Their findings, described in a Nature Communications publication released today, add to our current understanding of the dynamics of nuclear fusion and may enable more accurate predictions of other thermonuclear reactions critical to nuclear science applications.

Science Up-Close: Developing a Cookbook for Efficient Fusion Energy

Department of Energy, Office of Science

To develop a future fusion reactor, scientists need to understand how and why plasma in fusion experiments moves into a “high-confinement mode” where particles and heat can’t escape. Scientists at the Department of Energy’s Princeton Plasma Physics Laboratory simulated the transition into that mode starting from the most basic physics principles.

Found: A precise method for determining how waves and particles affect fusion reactions

Princeton Plasma Physics Laboratory

Like surfers catching ocean waves, particles within plasma can ride waves oscillating through the plasma during fusion energy experiments. Now a team of physicists led by PPPL has devised a faster method to determine how much this interaction contributes to efficiency loss in tokamaks.
