摘要

在考虑燃料耗竭的情况下，对激光产生的等离子体中的燃烧分数进行了计算。在 Floquet-Volkoff 框架中分析和计算了强场激光的增强作用，该框架在之前的一项研究中被证实为激光增强聚变截面提供了充分的理论预测[Phys. Rev. C 109, 044605 (2024)]。聚变过程考虑了三种不同的燃料，即氘-氚（DT）聚变、氘-氦聚变和质子-硼聚变。在考虑热分布和非热分布的理想和现实环境中，对它们的激光增强燃烧分数进行了比较。结果发现，在考虑的所有情况下，氘氦核聚变获得的燃烧分数相对增强最小，与前者相比，其余燃料获得的绝对增强不够明显。

Laser-enhanced fusion burn fractions for advanced fuels

Calculations for the burn fraction in a laser-created plasma are presented, taking fuel depletion into account. The enhancement from a strong-field laser is analyzed and calculated in the Floquet-Volkoff framework, which was verified to provide an adequate theoretical prediction for laser-enhanced fusion cross sections in a previous work [Phys. Rev. C 109, 044605 (2024)]. Three different fuels were considered for the fusion process, namely deuterium-tritium (DT) fusion, deuterium-helium fusion, and proton-boron fusion. Their laser-enhanced burn fractions are compared in idealistic and realistic settings, where both thermal and nonthermal distributions are considered. It is found that DT fusion gains the least relative enhancement to the burn fraction in all scenarios considered, and that the remaining fuels do not gain an absolute enhancement large enough to be appreciable in comparison with the former.
