Chris Wagner: The role of Eden Radioisotopes in the future of nuclear medicine
Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

A high-intensity, high-energy neutron source for fusion materials testing is proposed. Utilizing the 1H(t,n)3He neutron source reaction and bombarding a thick (totally absorbing) hydrogen-rich target with an intense beam of 21-MeV tritons provides a powerful continuous-energy-spectrum neutron source. The global spectrum of such a source is almost flat over the energy range from ∼1 to 14 MeV and exhibits a sharp energy cutoff level at 14.6 MeV. To meet near-term needs for fusion materials testing, a source concept is considered that involves multiple linear accelerator modules providing two 250-mA triton beams to bombard two water jet targets that face each other and irradiate the same test volume. Calculations of the source properties from well-established neutron production cross-section data for the 1H(t,n)3He reaction predict a test volume of 4.2 dm3 in which an average flux of ≥1 × 1014 n·cm-2·s-1 is achieved. The relevant properties of this source and the possibility of its realization, well within the limits of present technology, are discussed.
