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.

反应堆中微子应用和相干弹性中微子核散射

自 1970 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，随着能够进行高质量中微子光谱测量的吨级表面级探测器的演示，基于逆β衰变的探测器技术取得了巨大进步。与此同时，相干弹性中微子核散射已于 2017 年通过停止的π介子衰变中微子得到实验证实，并且有许多实验旨在观察这种与反应堆中微子的反应。这种反应的大横截面和无阈值性质使得考虑将其应用于核安全是合理的，在这里，我们首次对两种反应模式进行了直接比较。
