Abstract

Anisotropic distributions and deviations from velocity equilibrium play a crucial role in plasma physics and nuclear fusion processes. The emergence of high-energy tails in non-equilibrium distributions increases the population of energetic particles, thereby enhancing the probability of quantum tunneling and, consequently, fusion reaction rates. In this work, we investigate how the velocity-space anisotropy and deviations from the equilibrium affect the optimization of the fusion yield. Specifically, we analyze non-Maxwellian distribution models, including kappa and anisotropic kappa distributions, to evaluate their impact on fusion reactivity. Our results show that anisotropic distributions outperform isotropic ones at lower temperatures, whereas isotropic distributions dominate at higher temperatures. These findings provide new insights for the design of fusion devices and contribute to improving the efficiency of fusion processes.
