论文摘要
我们开发了一个简单的小规模实验，以测量$^{3} $ h的β衰变光谱。这项研究的目的是研究KEV地区无菌中微子的存在。 Tritium nuclei嵌入了1 $ \ times $ 1 $ \ times $ 1 cm $^3 $ lif Crystal，来自$^6 $ li（n，$α$）$^3 $ h反应。用40 mk的磁微含量计测量了在LIF晶体中吸收的β电子的能量。我们报告了一种新的样品制备，实验和分析$^3 $ H beta测量的方法。 10小时测量的光谱与预期的$^3 $ H beta衰变非常吻合。分析结果表明，该方法可用于搜索KEV规模的无菌中微子。
We developed a simple small-scale experiment to measure the beta decay spectrum of $^{3}$H. The aim of this research is to investigate the presence of sterile neutrinos in the keV region. Tritium nuclei were embedded in a 1$\times$1$\times$1 cm$^3$ LiF crystal from the $^6$Li(n,$α$)$^3$H reaction. The energy of the beta electrons absorbed in the LiF crystal was measured with a magnetic microcalorimeter at 40 mK. We report a new method of sample preparation, experiments, and analysis of $^3$H beta measurements. The spectrum of a 10-hour measurement agrees well with the expected spectrum of $^3$H beta decay. The analysis results indicate that this method can be used to search for keV-scale sterile neutrinos.
