摘要
νGeN实验装置，以低阈值锗光谱仪作为其基本元件，部署在加里宁核电站3号机组，距离反应堆堆芯中心11米。该实验旨在观察中微子在锗核上的相干弹性散射，以及寻找反中微子的电磁特性。本文基于98 kg day的reactor-OFF数据集估计了νGeN对反中微子磁矩的灵敏度。在90%的置信水平上，反应器开启时198 kg / d和反应器关闭时98 kg / d的期望限值为5.3 × 10−11 μB。对于1100 kg day的reactor-ON数据集，预测灵敏度为2.6 × 10−11 μB。
Sensitivity of νGeN Experiment to Magnetic Moment of Reactor Antineutrinos
The νGeN experimental setup, with a low-threshold germanium spectrometer as its basic element, is deployed at Unit 3 of the Kalinin Nuclear Power Plant, at a distance of 11 m from the centre of the reactor core. The experiment aims to observe coherent elastic scattering of neutrinos off germanium nuclei, as well as to search for antineutrino electromagnetic properties. This paper presents an estimate of νGeN sensitivity to the antineutrino magnetic moment based on the 98 kg day reactor-OFF dataset. The expected limit is 5.3 × 10−11 μB at the 90% confidence level for the exposition of 198 kg day with the reactor ON and 98 kg day with the reactor OFF. The projected sensitivity for the 1100 kg day reactor-ON dataset is 2.6 × 10−11 μB.
