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.

Protection of the direct-drive thermonuclear targets in the reaction chamber by containers of several kinds is considered. Thermoinsulation of the cryogenic thermonuclear fuel by a target ablator consisting of two layers separated by vacuum, low-density gas, or low-density foam is also considered. It is shown that the cones that provide a beam channel for heating the compressed fuel in some of the fast ignition, direct compression scenarios can also serve as effective wake shields protecting the fuel capsules.
