晶体损伤事件，如轨道和点缺陷已被用来记录和检测辐射很长一段时间，最近他们已被提议作为暗物质检测的一种手段。色心可以读出光学，我们提出了一个计划的基础上选择性平面照明显微镜微米级成像的大体积对应千克质量检测器。这类探测器将是被动的，并将在室温下工作，我们称之为被动低能光学色心核反冲（PALEOCCENE）探测方法。我们将这些概念应用于使用相干弹性中微子核散射（CENS）检测反应堆中微子。晶体损伤的形成能量本质上是在25 eV的顺序，导致同样低的核反冲阈值。这将使反应堆中微子CENS的观测与探测器小到10克。此外，对自旋相关的暗物质散射到GeV的暗物质质量的竞争性搜索是可能的。被动晶体探测器如果用于监测反应堆功率和限制钚的生产，对核不扩散保障也可能具有吸引力。拟议探测器的无源性质和小足迹意味着这些探测器可能非常适合公认的反应堆保障操作。
Crystal-damage events such as tracks and point defects have been used to record and detect radiation for a long time and recently they have been proposed as a means for dark-matter detection. Color centers can be read out optically and we propose a scheme based on selective plane illumination microscopy for micrometer-scale imaging of large volumes corresponding to kilogram mass detectors. This class of detectors would be passive and would operate at room temperature and we call this the passive low-energy optical color-center nuclear-recoil (PALEOCCENE) detection method. We apply these concepts to the detection of reactor neutrinos using coherent elastic neutrino nucleus scattering (CENS). Crystal-damage formation energies are intrinsically on the order of 25 eV, resulting in similarly low nuclear-recoil thresholds. This would enable the observation of reactor-neutrino CENS with detectors as small as 10 g. Additionally, a competitive search for spin-dependent dark-matter scattering down to a dark-matter mass ofGeV could be possible. Passive crystal detectors might also be attractive for nuclear-nonproliferation safeguards if used to monitor reactor power and to put limits on plutonium production. The passive nature and small footprint of the proposed detectors implies that these might fit well within accepted reactor-safeguards operations.
