摘要

水切伦科夫探测器（wcd）是探索高能天体物理现象的关键。它们为探测高能粒子提供了一种成本更低、更容易获得的替代空间仪器。这一贡献介绍了一种新的光电探测器配置，作为传统上使用的大型光电倍增管（pmt）的更小和更具成本效益的替代品。我们介绍了在莱斯特大学进行的测试，使用定制的水切伦科夫探测器-具有向下的3英寸PMT与移波长（WLS）板相结合。同时，正在进行GEANT4蒙特卡罗模拟，以模拟这种新配置的性能。该单元旨在识别wcd的强子事件，就像南方宽视场伽玛射线天文台（SWGO）设想的那样。

Exploring the high-energy universe with a novel photodetector configuration

Water Cherenkov detectors (WCDs) are key in exploring high-energy astrophysical phenomena. They offer a lower-cost and accessible alternative to space-based instruments for detecting high-energy particles. This contribution introduces a novel photodetector configuration as a smaller and cost-effective alternative to the traditionally used large photomultiplier tubes (PMTs). We present the tests performed at the University of Leicester, employing a custom-built water Cherenkov detector — featuring a downward-facing 3-inch PMT coupled with wavelength-shifting (WLS) plates.

In parallel, GEANT4 Monte Carlo simulations are being conducted to model the performance of this new configuration. The unit is designed to identify hadronic events for WCDs like those envisaged for the Southern Wide-field Gamma-ray Observatory (SWGO).

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
