摘要

The presence of lithium in a 3He plasma is shown to be a key parameter for enhancing energy production. In this research, a temporal model is employed to investigate the dynamics of 3He-6Li plasma and compare it with the 3He-3He rea3ction. Numerical solution of the time-dependent equations is used for studying burning process, considering all five reactions for the nine of particle species produced in the 3He-6Li reaction cycle. The results show that 1) synchrotron radiation losses exceed than bremsstrahlung losses in the considered scenario. 2) the peak power increases with lithium to helium ion density ratio 3) the self-heating is more pronounced in 3He-6Li plasma than the 3He-3He plasma.4) 3He-6Li plasma is more reactive than the 3He-3He plasma at similar total densities.5) higher lithium density results in a considerable increase in fusion power. 6) to achieve an identical energy release, the 3He-6Li plasma requires a shorter confinement time than 3He-3He plasma.7) despite high initial temperatures, ions and electrons exhibit limited additional heating.
