Abstract:
In recent years, various designs for controlled thermonuclear fusion based on the p۱۱B reaction have been reviewed and optimized. In this article, to innovate in achieving a better power and energy gain of neutron-free p۱۱B fusion reaction, the improvement of the cross-section and also the kinetic effects. Then, the effects of bremsstrahlung radiation and ion and electron energy exchange rate have been evaluated by introducing relativistic effects and its role on improving fusion energy gain. As a result, the temperature of the electron is kept lower than that of the ion, which improves fuel performance. Finally, it leads to an increase in the number of protons at higher energies compared to the pure Maxwellian distribution and it causes a significant increase in reactivity compared to previous research. Also, the number of alpha particles obtained through calculations coincides with the latest research and leads to an enhancement of approximately ۱۳%. This means that by improving the fusion cross-section of p۱۱B, our calculations show that considering the avalanche effects, the range of achievable energy gain in the temperature range of ۳۰۰ to ۵۰۰ keV and the stable characteristic time of ۰.۶۴ ps reaches ۸۹ to ۱۱۱. While in the same temperature range and with the stable characteristic time of ۰.۷۴ ps, regardless of the improved cross-section, the energy gain range is ۷۵ to ۹۸.
