利用SiPMs直接搜索暗物质的挑战

Challenges for dark matter direct search with SiPMs

Alessandro Razeto, Nicola Rossi

摘要:

液态氙和液态氩探测器正在引领直接暗物质搜索,并有望成为下一代超灵敏大质量探测器的候选技术。目前,这些实验中的闪烁光探测都是基于超纯低噪声光电倍增管。为了克服未来暗物质实验的极端放射性纯度、成本和技术可行性方面的问题,新型的基于SiPM的光探测器模块看起来是有希望的候选者,能够取代目前的光探测技术。然而,SiPM的内在特征可能会限制目前的预期。特别是,干涉现象,特别是与光学相关噪声有关的干涉现象,会降低能量和脉冲形状分辨率。因此,必须相应地重新考虑未来探测器的预计灵敏度。

英文摘要:

Liquid xenon and liquid argon detectors are leading the direct dark matter search and are expected to be the candidate technology for the forthcoming generation of ultra-sensitive large-mass detectors. At present, the scintillation light detection in those experiments is based on ultra-pure low-noise photo-multipliers. To overcome the issues in terms of the extreme radio-purity, costs, and technological feasibility of the future dark matter experiments, the novel SiPM-based photo-detector modules look promising candidates, capable of replacing the present light detection technology. However, the intrinsic features of SiPMs may limit the present expectations. In particular, interfering phenomena, especially related to the optical correlated noise, can degrade the energy and pulse shape resolutions. As a consequence, the projected sensitivity of the future detectors has to be reconsidered accordingly.
