Temperature anisotropy in the magneto-inertial fusion process of P11B degenerate fuel

This paper investigates the effect of temperature anisotropy on the reactivity and ignition of P-¹¹B degenerate fuel pellet in the Magneto-Inertial Fusion (MIF) process. Energy balance equations are solved to analyze the impact of temperature anisotropy and degeneracy parameter variations on ignition dynamics. The results demonstrate that increasing the degeneracy parameter amplifies fusion power while reducing bremsstrahlung power. Temperature anisotropy below unity (β < 1) enhances system stability, creating favorable conditions for ignition and achieving higher energy gain. During the pre-pulse phase, the system achieves its highest energy gain, and as time progresses, the gain gradually decreases. An increase in temperature anisotropy leads to the maximum energy gain occurring at a later time. The findings contribute to addressing the challenges associated with P-11B fusion and improving the prospects of achieving efficient fusion reactions in magneto-inertial fusion.
