项目摘要

The LBNF/DUNE project is a global flagship initiative in high-energy particle physics that addresses key questions on the origin and structure of the universe. The long-baseline neutrino facility (LBNF) will be the world's most intense high-energy neutrino beam. It will fire neutrinos 1300 km from Fermilab in Illinois towards the 70,000 ton DUNE detector in South Dakota in order to study neutrino oscillations. DUNE will be the first large-scale US-hostedexperiment run as a truly international project. DUNE has broad support from the global particle physics community in the US and Europe and with growing interest in developing countries; DUNE currently is a scientific collaboration of over 950 collaborators from 30 nations, with overall UK leadership.LBNF/DUNE will undertake a game-changing programme of neutrino physics. Its highest-level scientific goals target big questions in physics: 1) Discovery and measurements of neutrino CP violation. This subtle difference between neutrinos and antineutrinos could be responsible for the remaining matter in the universe;2) Precision neutrino physics, including the definitive determination of the mass hierarchy;3) Search for new physics beyond the current understanding of neutrino oscillations;4) Observation of the electron neutrino burst from a galactic core-collapse supernova, providing a real-time probe of neutron star and possibly black hole formation;5) Search for proton decay, expected in most models of new physics, but not yet observed.The UK plans to make a major contribution to the construction of the massive DUNE far detector, through a partnership between UK universities, UK national laboratories and UK industry. In this proposal UK scientists are requesting resources to prototype the production processes for the construction of detector elements for this global scientific project.

LBNF/Dune项目是一项全球旗舰倡议，用于高能粒子物理学，涉及有关宇宙起源和结构的关键问题。长基线中微子设施（LBNF）将是世界上最激烈的高能中微子束。它将从伊利诺伊州的费米拉布（Fermilab）向南达科他州的70,000吨沙丘探测器发射1300公里的中微子，以研究中微子振荡。 Dune将是第一个真正的国际项目大规模的美国托管特有跑步。沙丘得到了美国和欧洲全球粒子物理界的广泛支持，并且对发展中国家的兴趣越来越大； Dune目前是来自30个国家的950多名合作者的科学合作，与英国的整体领导。LBNF/Dune将开展改变游戏中微子物理学计划的计划。其最高级别的科学目标针对物理学中的大问题：1）违反中微子CP的发现和测量。 This subtle difference between neutrinos and antineutrinos could be responsible for the remaining matter in the universe;2) Precision neutrino physics, including the definitive determination of the mass hierarchy;3) Search for new physics beyond the current understanding of neutrino oscillations;4) Observation of the electron neutrino burst from a galactic core-collapse supernova, providing a real-time probe of neutron star and possibly black hole编队； 5）寻找质子衰变，预计在大多数新物理学模型中，但尚未观察到。英国计划通过英国大学，英国国家实验室和英国工业之间的合作伙伴关系，为大型沙丘远处检测器的建设做出重大贡献。在这项提案中，英国科学家正在要求资源原型为该全球科学项目构建探测器元素的生产过程。
