论文摘要
液体氙气和液体氩探测器正在领导直接的暗物质搜索，并有望成为即将产生的超敏感大质量探测器的候选技术。目前，这些实验中的闪烁光检测基于超纯净的低噪声照相。为了克服未来暗物质实验的极端无线电，成本和技术可行性的问题，基于SIPM的新型光探测器模块看起来很有希望的候选人，能够替代当前的光检测技术。但是，SIPMS的内在特征可能会限制当前的期望。特别是，干扰现象，特别是与光学相关噪声有关的现象会降解能量和脉搏形状分辨率。结果，必须相应地重新考虑未来探测器的预计灵敏度。
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.
