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.

Amorphous carbon and single crystal silicon collector probes were inserted into the bundle divertor of DITE on the electron drift side. Onto the carbon, 2.7×1016 atoms/cm2 antimony was evaporated and for silicon 5×1015 atoms/cm2, Sb+ implantation was carried out prior to the exposure to plasma. Thus these probes not only collected impurities but were able to provide information on the material loss as well. Using RBS analysis it turned out that the predominant species detected were carbon, oxygen and stainless steel components. Other impurities such as Ti, S, Cl, Mo, Cu and Pb were also found. Their radial distribution is reported. On evaporated probes an Sb loss with typical value of 3 to 5×1015 atoms/cm2 discharge was observed.
