摘要:

基于\ce{^{6}Li}的中子俘获原理,我们设计并测试了一个大面积(0.15~ mPDMATHABMM)中子探测器。中子探测器的设计已被优化的目的标记的散射角的千电子伏尺度的中子。这些中子探测器将用于校准暗物质和相干弹性中微子核散射(CE $ν$ NS)探测器中的低能($<$ 100 eV)核反冲。我们描述了原型的设计,构造和表征。原型设计为在相关$\mathcal{O}$(keV)中子能量下具有25%的$\sim$标记效率,平均捕获时间为$\sim$ 17 $~μ$ s。原型的特点是使用\ce{^{252}Cf}中子源和协议的模拟观察到在百分之几的水平。

英文摘要:

We have designed and tested a large-area (0.15~m$^2$) neutron detector based on neutron capture on \ce{^{6}Li}. The neutron detector design has been optimized for the purpose of tagging the scattering angle of keV-scale neutrons. These neutron detectors would be employed to calibrate the low-energy ($<$100 eV) nuclear recoil in detectors for dark matter and coherent elastic neutrino nucleus scattering (CE$ν$NS). We describe the design, construction, and characterization of a prototype. The prototype is designed to have a tagging efficiency of $\sim$25\% at the relevant $\mathcal{O}$(keV) neutron energies, and with a mean capture time of $\sim$17$~μ$s. The prototype was characterized using a \ce{^{252}Cf} neutron source and agreement with the simulation was observed within a few percent level.
