项目摘要

Dark matter and neutrino detections share standard technologies and methodologies, specifically, Liquid Argon Time Projection Chambres (LArTPCs) and photodetection systems. This project involves the development of 2 types of photodetection systems for LArTPCs; the Silicon Photomutiples (SiPMs) for Darkside-20's veto and the Timepix-based cameras in the ARIADNE experiment. The unique facility at Liverpool is dedicated to the development of progressive new technologies for Liquid Argon based dark matter and neutrino experiments. To detect dark matter particles and neutrinos large and sensitive particle detectors are needed. LArTPCs are some of the best detectors for the detection of neutrino interactions and dark matter particles. They combine highly accurate calorimetry and tracking and are capable of reaching very large active volumes. For DarkSide-20k, the research involves the development of the SiPMs in the outer detector called the "neutron veto"; it will contain single-phase liquid Argon, which will also be equipped with gadolinium panels to capture neutrons. While characterising the SiPM photodetection units (PDUs), it is crucial to maximising their light yield as they will be utilised for vetoing and particle identifications. A 900-litre cryostat will be built at the University of Liverpool to study the cryogenic characterisation of the PDUs.The ARIADNE experiment consists of a 1-ton dual-phase LArTPC situated at the University of Liverpool. It uses the Timepix's novel technology to acquire images of particle tracks created from the light in the gas phase. ARIADNE has photographic capabilities that can enhance the future physics potentials of neutrino experiments such as the DUNE experiment.

暗物质和中微子探测共享标准技术和方法，具体地说，是液体氩时间投影室(LArTPC)和光探测系统。该项目包括为LArTPC开发两种类型的光探测系统：用于Darkside-20‘S否决权的硅光电倍增管(SiPM)和Ariadne实验中的基于Timepix的相机。利物浦的这个独特的设施致力于开发基于液态Ar的暗物质和中微子实验的先进新技术。要探测暗物质粒子和中微子，需要大而灵敏的粒子探测器。LArTPC是探测中微子相互作用和暗物质粒子的最佳探测器之一。它们结合了高度精确的量热和跟踪，能够达到非常大的活跃量。对于Darkside-20K，这项研究涉及在外部探测器中开发名为“中子否决权”的SiPM；它将包含单相液体Argon，它还将配备用于捕获中子的Gd面板。在描述SiPM光电检测单元(PDU)的同时，最大限度地提高它们的光产额是至关重要的，因为它们将用于否决和颗粒识别。利物浦大学将建造一个900升的低温恒温器来研究PDU的低温特性。Ariadne实验包括位于利物浦大学的一个1吨重的双相LArTPC。它使用Timepix的新技术来获取气相中光产生的粒子轨迹的图像。阿里阿德涅拥有摄影能力，可以增强未来中微子实验的物理潜力，例如沙丘实验。
