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.

The effect of reducing the aspect ratio on the confinement of deuterium-tritium fusion products, i.e., alpha particles, in tokamaks is discussed. It is shown that for low-aspect-ratio tokamak reactors, the alpha-particle heating efficiency can be similar to conventional tokamaks; at the same time, the alpha-particle confinement time can be much shorter than that of conventional tokamaks. Thus, one can facilitate alpha-particle ash removal while maintaining high alpha-particle heating efficiency by reducing the aspect ratio.
