DUNE (the Deep Underground Neutrino Experiment) is hosted at Fermilab USA. It is being designed and will be operated by a collaboration of over 1,000 physicists across 32 countries from Asia, Europe and the Americas and it will be the world's most advanced neutrino observatory. DUNE aims to advance our understanding of the origin and structure of the universe by allowing the study of the behaviour of particles called neutrinos and their antimatter counterparts, antineutrinos. This could provide insight as to why we live in a matter-dominated universe suitable for life as we know it. DUNE will also watch for supernova neutrinos produced when a star explodes, which will allow scientists to observe the formation of neutron stars and black holes, and will investigate whether protons live forever or eventually decay, bringing us closer to fulfilling Einstein's dream of a grand unified theory.The DUNE detector will comprise four large detector modules each containing 17,000 kg of liquid argon where neutrino interactions will be captured. There is still much scope for optimising the readout of these detectors. In the UK we have developed a revolutionary technology based on ultra-fast imaging cameras capable of continuous streaming and therefore continuous capturing of particle interactions with nano-second resolution. This is equivalent to having a camera capable of recording several million frames per second. This is a powerful system that takes the field away from the old technologies developed in the 70s which are based on reading signals from complex interwoven long wires. Our camera-based system will allow us to capture even lower energy particles (thus enhancing the physics potential), view interactions with millimetre resolution, and will simplify the huge engineering challenges that this colossal experiment faces while at the same time bringing the cost down considerably. The current DUNE experiment is actively seeking new technologies for the final modules for which the final design has not yet been decided. The objective of this proposal is to take the technology that we have demonstrated in Liverpool with the ARIADNE experiment to a larger scale experiment at CERN which will provide feasibility studies and progress the technology towards implementation within the DUNE experiment.

DUNE（Deep Underground Neutrino Experiment）位于美国费米实验室。它将由来自亚洲、欧洲和美洲32个国家的1,000多名物理学家合作设计和操作，它将是世界上最先进的中微子天文台。DUNE旨在通过研究称为中微子及其反物质对应物反中微子的粒子的行为来促进我们对宇宙起源和结构的理解。这可能会让我们深入了解为什么我们生活在一个适合生命存在的物质主导的宇宙中。DUNE还将观察星星爆炸时产生的超新星中微子，这将使科学家能够观察中子星和黑洞的形成，并将研究质子是永生还是最终衰变，DUNE探测器将包括四个大型探测器模块，每个模块包含17，000公斤的液态氩，中微子相互作用将被捕获。仍然有很大的空间来优化这些探测器的读数。在英国，我们开发了一种基于超快成像相机的革命性技术，该相机能够连续流式传输，从而以纳秒级分辨率连续捕获粒子相互作用。这相当于拥有一台能够每秒记录数百万帧的相机。这是一个功能强大的系统，它使该领域远离了70年代开发的旧技术，这些技术基于从复杂的交织长导线中阅读信号。我们基于相机的系统将使我们能够捕获更低能量的粒子（从而增强物理潜力），以毫米分辨率查看相互作用，并将简化这个巨大实验所面临的巨大工程挑战，同时大大降低成本。目前的DUNE实验正在积极寻求最后模块的新技术，其最终设计尚未决定。本提案的目的是将我们在利物浦通过ARIADNE实验展示的技术用于CERN的更大规模实验，该实验将提供可行性研究，并在DUNE实验中实现该技术。
