我们报告的单光子传感器，采用波长移动和光导技术，以最大限度地提高收集面积，同时最大限度地减少暗噪声率的发展状况。该传感器是专为嵌入在惰性和冷，低放射性和紫外线透明冰作为检测介质，如冰立方-Gen 2或云母的冰切伦科夫中微子探测器的应用。目标是降低能量阈值，并增加中微子望远镜的能量分辨率和否决能力，与冰立方中使用的光学传感器类似。拟议的传感器捕获波长在250 nm至400 nm之间的光子。这些光子通过施加到90 mm直径聚合物管的波长偏移涂层以400 nm以上的波长重新发射。该管通过全内反射将光导向小直径PMT。通过缩放来自较小实验室原型的结果，估计所提出的切伦科夫光谱检测器的总效率超过标准IceCube光学模块的总效率。将讨论原型开发的状态及其主要部件的性能。
We report on the development status of a single-photon sensor that employs wavelength-shifting and light-guiding techniques to maximize the collection area while minimizing the dark noise rate. The sensor is tailored towards application in ice-Cherenkov neutrino detectors embedded in inert and cold, low-radioactivity and UV transparent ice as a detection medium, such as IceCube-Gen2 or MICA. The goal is to decrease the energy threshold as well as to increase the energy resolution and the vetoing capability of the neutrino telescope, when compared to a setup with optical sensors similar to those used in IceCube. The proposed sensor captures photons with wavelengths between 250 nm and 400 nm. These photons are re-emitted with wavelengths above 400 nm by a wavelength shifting coating applied to a 90 mm diameter polymer tube. The tube guides the light towards a small-diameter PMT via total internal reflection. By scaling the results from smaller laboratory prototypes, the total efficiency of the proposed detector for a Cherenkov spectrum is estimated to exceed that of a standard IceCube optical module. The status of the prototype development and the performance of its main components will be discussed.
