论文摘要
NOMOS是一种新型的动量光谱仪，我们旨在以高精度测量带电中子β衰减产品的光谱。质子和电子光谱的形状可以分别用于测定电子抗antineutrino相关系数$ a $和FIELZ干扰项$ b $。这些可观察物可以依次用于测试粒子物理的标准模型并搜索其扩展。 Nomos利用弯曲磁场中存在的$ r \ times b $漂移效应，该磁场会根据其动量分散带电的颗粒。在本文中，我们报告了针对磁铁设计和检测系统进行的一些最新研究。
NoMoS is a novel momentum spectrometer with which we aim to measure the spectra of the charged neutron beta decay products with high precision. The shape of the proton and electron spectra can inter alia be used for the determination of the electron-antineutrino correlation coefficient $a$ and the Fierz interference term $b$, respectively. These observables can in turn be used to test the Standard Model of Particle Physics and to search for extensions thereof. NoMoS utilizes the $R \times B$ drift effect present in curved magnetic fields, which disperses charged particles according to their momentum. In this paper, we report on selected recent investigations that were conducted with regard to the magnet design and the detection system.
