自20世纪70年代以来，人们一直在讨论中微子探测在核安全方面的潜在应用。近年来，基于逆贝塔衰变的探测器技术取得了很大进展，展示了能够进行高质量中微子光谱测量的吨级表面水平探测器。与此同时，相干弹性中微子核散射已经在2017年被实验证实，它是由被阻止的介子衰变产生的中微子，而且有许多实验旨在观察这种反应与反应堆中微子的反应。这种反应的大截面和无阈值特性使其有可能应用于核安全，在这里，我们首次对这两种反应模式进行了直接比较。
Potential applications of neutrino detection to nuclear security have been discussed since the 1970s. Recent years have seen great progress in detector technologies based on inverse beta decay, with the demonstration of ton-scale surface-level detectors capable of high quality neutrino spectrum measurements. At the same time coherent elastic neutrino nucleus scattering has been experimentally confirmed in 2017 with neutrinos from stopped pion decay and there is a number of experiments aimed at seeing this reaction with reactor neutrinos. The large cross section and threshold-less nature of this reaction make it plausible to consider it for applications to nuclear security and here, we present a first direct comparison of the two reaction modes.
