IceCube has discovered the high-energy astrophysical neutrino flux, opening a new window to observe the Universe. However, the origin of this emission still needs to be determined. To discover the sources of high-energy neutrinos and probe the nature of high-energy particle accelerators, we need to build a larger-scale high-energy neutrino telescope that will allow us to better combine neutrino and electromagnetic wave observations. The proposed international collaboration aims to develop cost-efficient optical sensor modules using commercially available wavelength-shifting fibres. Using commercially mass-producible fibres as the photon-capturing devices, this instrument will have smaller optical sensors and glass vessels than are currently deployed in existing neutrino telescopes. This reduces the cost of detector modules as well as the background from the impurities from the glass. The international collaborators provide essential expertise on the overall detector simulation and development of new sensor modules. The shared infrastructure in this proposed collaboration will allow us to test the feasibility of the proposed devices. The proposed international R&D research will provide excellent training opportunities for highly qualified personnel to obtain highly valuable skills for both academic and industrial careers. Working with collaborators with a strong history of supporting equity, diversity, and inclusion will expand HQP's learning of the topics.

IceCube发现了高能天体物理学中微子流，打开了观察宇宙的新窗口。然而，这种排放的来源仍然需要确定。为了发现高能中微子的来源，探测高能粒子加速器的本质，我们需要建造一个更大规模的高能中微子望远镜，使我们能够更好地将中微子和电磁波观测联合收割机结合起来。拟议中的国际合作旨在使用市售的波长转换光纤开发具有成本效益的光学传感器模块。使用商业上可大规模生产的光纤作为光子捕获设备，该仪器将拥有比现有中微子望远镜更小的光学传感器和玻璃容器。这降低了检测器模块的成本以及来自玻璃的杂质的背景。国际合作者为整个探测器模拟和新传感器模块的开发提供必要的专业知识。这项合作计划中的共享基础设施将使我们能够测试拟议设备的可行性。拟议的国际研发研究将为高素质人员提供极好的培训机会，以获得学术和工业职业生涯中非常宝贵的技能。与在支持公平、多样性和包容性方面有着悠久历史的合作者合作，将扩大HQP对这些主题的学习。
