摘要:

近期对相干弹性中微子-原子核散射(CE$ν$NS)的探测,开启了使用中微子借助小型探测器探索超出标准模型物理的可能性。然而,CE$ν$NS过程产生几keV量级的信号,需要极其灵敏的探测器技术。欧洲散裂中子源(ESS)被确定为低能中微子的最佳来源,为全面探索CE$ν$NS的所有唯象应用提供了机会。目前正开发多种不同的探测器方案以部署于ESS。这些下一代技术将能以比现有探测器更低的能量阈值和更好的能量分辨率观测该过程。结合各项观测结果,将能对CE$ν$NS信号进行完整的唯象利用。特别是,得益于ESS预期的高中微子通量,这些测量将不受统计学限制。本文介绍了当前在ESS上探测CE$ν$NS的主要项目:使用充入不同惰性气体的高压气体TPC的GanESS项目;采用低温无掺杂CsI晶体的C$^{\circ}\\!$sI项目;以及p型点接触HPGe探测器。

英文摘要:

The recent detection of coherent elastic neutrino-nucleus scattering (CE$ν$NS) opens the possibility to use neutrinos to explore physics beyond standard model, with small-size detectors. However, the CE$ν$NS process generates signals at the few keV level, requiring very sensitive detector technologies. The European Spallation Source (ESS) has been identified as an optimal source of low energy neutrinos, offering an opportunity for a definitive exploration of all phenomenological applications of CE$ν$NS. A number of different detector approaches are currently under development for deployment at ESS. These next-generation technologies will be able to observe the process with lower energy threshold and better energy resolution than current detectors. The combination of their observations will allow for a complete phenomenological exploitation of the CE$ν$NS signal. In particular, these measurements will not be statistically-limited, a result of the large neutrino flux expected at the ESS. The main projects currently being developed to detect CE$ν$NS at the ESS are presented: the GanESS project which will use high pressure gas TPC filled with different noble gases; the C$^{\circ}\!$sI project, which employs cryogenic undoped CsI crystals; and p-type point contact HPGe detectors.
