Large Area Fast Timing Photon Sensors for Cherenkov Detectors in Neutrino Physics and Particle Identification

切伦科夫光是当带电粒子穿过物质的速度快于该物质中的光速时发出的。这种微弱的光源提供了有关粒子、其路径和速度的宝贵信息。因此，使用切伦科夫光的探测器系统一直是许多科学发现的重要实验工具，从天文学到中微子物理，再到核物理学家和粒子物理学家探索的亚原子世界的详细了解。科学理解的进步与下一代实验仪器的发展齐头并进。在中微子物理领域，计划在本十年内在约克郡的博尔比地下实验室安装一个大型地下探测器。对于我们理解夸克和胶子共同作用形成我们周围的核子和原子核的方式，关键的下一步将由美国计划中的电子离子对撞机完成。这两个项目都将依靠下一代切伦科夫探测器来实现其科学潜力。从切伦科夫光中探测微弱信号并从该来源提取最大数量的信息需要覆盖大面积的可见光光子传感器，同时仍提供非常好的位置和时间分辨率。他们必须在具有挑战性的环境中高效运作。最近开发了一种基于大型瓷砖中的微通道板的新设备-LAPPD，并已可用于评估。该项目将详细研究该装置的特性和性能，并针对基础物理研究的下一代切伦科夫探测器的挑战性需求评估其性能。

Cherenkov light is emitted when a charged particle is traversing a material faster then the speed of light in this material. This faint source of light provides invaluable information on the particle, its path and speed. As such, detector systems using Cherenkov light have been crucial experimental tools for many scientific discoveries, from Astronomy to neutrino physics to the detailed understanding of the subatomic world explored by nuclear and particle physicists.Advances in scientific understanding go hand in hand with advances in the development of instrumentation for the next generation of experiments. In the field of neutrino physics, a large underground detector is planned to be installed in this decade in the Boulby Underground Laboratory in Yorkshire. A crucial next step for our understanding of the ways quarks and gluons act together to form the nucleons and nuclei around us will be made by the planned Electron Ion Collider in the USA. Both project will rely on the next generation of Cherenkov detectors to fulfil their science potential.The detection of the faint signal form Cherenkov light and extraction of the maximum amount of information from this source requires visible light photon sensors covering large area while still providing a very good position and time resolution. They have to operate efficiently in challenging circumstances. A new device based on Micro-Channel plates in a large tile, the LAPPD, has been recently developed and has become available for evaluation. This project will study the properties and performance of this device in detail and evaluate its performance with respect to the challenging demands of the next generation of Cherenkov detectors for fundamental physics research.
