论文摘要
使用梁法对自由中子的寿命的最新测量具有8.7 s（4 $σ$）的差异，并具有UCN测量值。 BL3实验的目的是改善该测量的统计误差，并有助于排除系统的不确定性作为差异的解释。具有平坦响应的特征良好的中子通量检测器是必不可少的，因为中子通量线性进入中子寿命。我将提出一个新的检测器几何优化，并在中子位置均匀接受至第六阶。
The recent measurement of the lifetime of the free neutron using the beam method has an 8.7 s (4$σ$) discrepancy with UCN measurements. The goal of the BL3 experiment is to improve the statistical error of this measurement and help rule out systematic uncertainties as an explanation for the discrepancy. A well-characterized neutron flux detector with flat response is essential, since the neutron flux enters linearly into the neutron lifetime. I will present a new detector geometry optimization with uniform acceptance up to sixth order in neutron position.
