Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A scenario to verify the knock-on tail formation by energetic protons and the resulting enhancement of the fractional ion heating by using 3He-containing deuterium plasma is presented. On the basis of the Boltzmann-Fokker-Planck (BFP) model, the knock-on tail formation in deuteron distribution function due to nuclear plus interference (NI) scattering of fusion-produced energetic protons and the resulting modification of the neutron emission spectrum are examined. A recognizable change in the energetic-neutron emission rate due to the knock-on tail formation depending on the external 3He inclusion is shown. Another possible scenario to ascertain the enhancement of ion-heating by using -ray-generating 6Li+D reaction is also presented and discussed.
