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 feasibility study for the heavy ion beam probe on the Wendelstein 7-X (W7-X) stellarator was done to provide measurements of the radial profiles of plasma potential, density, and their fluctuations. Calculations of probing Tl+ beam trajectories were done for the various W7-X magnetic configurations with Btor = 2.5 T. They show that satisfactory access is possible for K11-N11 port combination. The trajectory optimization aiming for the maximal plasma observation was done for the chosen port combination.
