论文摘要
融合设备中的中子产量不仅取决于动力学曲线，而且还决定了快速离子减速分布。在这项工作中，我们研究了Wendelstein 7-X（W7-X）恒星剂中磁性构型对未来氘等离子体中中子产生速率的影响。中性束注射，梁和Triton减速分布以及融合反应性通过ASCOT套件进行模拟。结果表明，磁性构型对来自热核和梁目标融合的2.45 MeV中子的产生只有很小的影响。发现14.1 MEV中子的生产率在$ 1.49 \ times 10^{12} $ $ \ Mathrm {s}^{ - 1} $和$ 1.67 \ times 10^{12} $ $ \ Mathrm {s}^{s}^{ - 1} $的估计中，虽然是在时间上估计的，但仅适用于A grive，虽然可以估计A gription，否高性能排放。
Neutron production rates in fusion devices are determined not only by the kinetic profiles but also the fast ion slowing-down distributions. In this work, we investigate the effect of magnetic configuration on neutron production rates in future deuterium plasmas in the Wendelstein 7-X (W7-X) stellarator. The neutral beam injection, beam and triton slowing-down distributions, and the fusion reactivity are simulated with the ASCOT suite of codes. The results indicate that the magnetic configuration has only a small effect on the production of 2.45 MeV neutrons from thermonuclear and beam-target fusion. The 14.1 MeV neutron production rates were found to be between $1.49 \times 10^{12}$ $\mathrm{s}^{-1}$ and $1.67 \times 10^{12}$ $\mathrm{s}^{-1}$, which is estimated to be sufficient for a time-resolved detection using a scintillating fiber detector, although only in high-performance discharges.
