Spin-polarized fusion fuel with enhanced reactivity and isotropic emission
Fusion reaction rates and the angular distribution of emitted products, such as neutrons and alpha particles, are significantly influenced by the spin states of the fuel nuclei, including deuterium, tritium, and helium-3. While the selective preparation of nuclei in specific spin states can enhance fusion reaction rates, this typically results in anisotropic...

Spin-Polarized Fuels for Enhanced Tritium Burn Efficiency in Fusion Energy Systems
Magnetic confinement fusion power plants face a fundamental challenge in efficiently utilizing tritium fuel, a critical and limited resource. While increasing tritium burn efficiency (TBE)—the fraction of injected tritium that fuses—is desirable for fuel self-sufficiency and reducing inventory, existing approaches encounter an inherent trade-off:...
