论文摘要
我们研究了一个假设，即能量积累和随后在NAI（TL）中的释放可能导致脉冲能量状态中的脉搏样事件，这是晶体制造公司Saint-Gobain提出的这种现象，后者为Dama-Libra提供了晶体。虽然我们观察到将其暴露于紫外线后3英寸NAI（TL）晶体中的延迟持续的光发射，但延迟的光主要由彼此之间无关的单个光子组成。我们还观察到在脉冲辐射和大型电离事件之后，我们还发现了延迟的延迟，我们发现了延迟的延迟。光子排放。
We investigate a hypothesis that energy accumulation and the subsequent release in NaI(Tl) may lead to pulse-like events in the few-keV energy regime, a phenomenon suggested by the crystal manufacturing company Saint-Gobain, who provided the crystals for DAMA-LIBRA. While we observed delayed long-lasting light emission in a 3" NaI(Tl) crystal after exposing it to UV light, the delayed light consists primarily of single photons that are uncorrelated with each other. We also observe delayed light emission in NaI(Tl) following gamma radiation and large ionization events like cosmic-ray muons. We found that irradiating the crystal with red light after UV exposure significantly suppressed delayed photon emissions.
