| Title | Polarized Fusion and Potential in situ Tests of Fuel Polarization Survival in a Tokamak Plasma | ||||
| Abstract | The use of spin-polarized fusion fuels would provide a significant boost towards the ignition of a burning plasma. The cross section for the primary fusion fuel in a tokamak reactor, D+T /rightarrow ?+n, would be increased by a factor of 1.5 if the fuels were spin polarized parallel to the local field, rather than randomly oriented. Furthermore, our simulations show that additional non-linear gains in power would accompany this increase in large-scale machines such as ITER, due to increased alpha heating. The potential realization of such benefits rests on the crucial question of the survival of spin polarizations for periods comparable to the particle confinement time. During an initial peak of interest in such options during the 1980s, calculations predicted that polarizations could in fact survive a plasma environment, although concerns persisted regarding the cumulative impacts of wall recycling. In that era, the technical challenges of preparing and handling polarized materials pr | ||||
