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 design and a method for the fabrication of a NIF-sized beryllium capsule have been developed. The approach involves machining two halves of the 2.2 mm target from a piece of bulk beryllium copper alloy, joining the two halves under atmosphere, and finish machining the outer dimensions after joining. This design allows for the filling of the capsule either during joining or afterward using either permeation or a drill-and-plug technique. The capsules produced so far have had excellent bond joint quality and were dimensionally very close to the specifications. Needing improvement are the surface finishes, both interior and exterior of the shell.
