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.

We report results of modeling and experiments on infrared heated deuterium-hydride (HD) layers in hohlraums. A 2 mm diameter, 40 μm thick shell with 100–400 μm thick HD ice inside a NIF scale gold hohlraum is heated by pumping the HD vibrational-rotational bands. Models indicate control of the lowmode layer shape by adjusting the infrared distribution along the hohlraum walls. We have experimentally demonstrated control of the layer symmetry perpendicular to the hohlraum axis.
