Driven by technological innovation and escalating demand for diagnostics and treatments, nuclear medicine is a rapidly expanding global market. However, critical supply chain issues—specifically the United States' heavy reliance on imported medical isotope precursors—threaten this growth. To address this challenge, we developed a novel superheated ion source to improve upon existing electromagnetic isotope separation technology.

To address U.S. reliance on imported medical isotope precursors, a novel superheated ion source was developed to enhance electromagnetic isotope separation, resulting in a patent application and a submitted paper. The ion source increased beam current from 0.5 mA to 3.5 mA (7x improvement) and increased maximum operating temperatures from 1000°C to 2100°C through optimized materials selection and source geometry.
