项目摘要

In September 2017, the UK announced a £65m collaborative investment as part of a long history of UK research collaboration with the US, which is the first major project of the wider UK-US Science and Technology agreement. UK Universities and Science Minister Jo Johnson signed the agreement with the US Energy Department to invest the sum in the Long-Baseline Neutrino Facility (LBNF) and the Deep Underground Neutrino Experiment (DUNE). DUNE will study the properties of neutrinos, which could help explain more about how the universe works and why matter exists at all. This investment is a significant step which will secure future access for UK scientists to the international DUNE experiment. Investing in the next generation of detectors, like DUNE, helps the UK to maintain its world-leading position in science research and continue to develop skills in new cutting-edge technologies. STFC will manage the UK's investment in the international facility, giving UK scientists and engineers the chance to take a leading role in the management and development of the DUNE far detector, the LBNF beam line and associated PIP-II accelerator technologies, thereby strengthening the UK's strategic partnership with FNAL in the USA. The UK's delivery of critical SRF accelerator systems for PIP-II will significantly enhance the world class skills already developed over many years in the field of SRF technology at Daresbury Laboratory, providing advanced preparation and testing infrastructure which can enable even larger scale and more complex technical system delivery for future national and international priority programmes. Such a UK delivery will also significantly escalate STFC's international leadership and prominence in this highly specialised field of expertise. As part of the UK's In Kind Contribution (IKC) to the Deep Underground Neutrino Experiment, STFC will provide superconducting RF (SRF) cavities and assembled cryomodules for the new PIP-II SRF Linac at Fermilab, building on experience gained from the ESS high-beta cavity programme and the HL-LHC prototype cryomodule assembly which are both funded by the UK to conclude at Daresbury Laboratory in FY20/21. The scope of the expected delivery to FNAL will be to enhance UK industry fabrication capability for SRF accelerating structures, procurement of high purity niobium sheets and HB650 cavity fabrication to FNAL specifications and to validate the performance of these structures using the existing SRF testing infrastructure available at Daresbury Laboratory. Once testing has confirmed performance compliance, the cavities will be assembled and integrated into cryomodules using new assembly infrastructure to be provisioned, which will accommodate each 10m-long cryogenic vessel. Assembly of three HB650 cryomodules, each comprising six 650MHz high beta cavities will be prepared, which will then be shipped to FNAL for high power testing, prior to installation on the PIP-II accelerator.

2017 年 9 月，英国宣布一项 6500 万英镑的合作投资，作为英国与美国长期研究合作的一部分，这是更广泛的英美科学技术协议的第一个重大项目。与美国能源部签署协议，投资长基线中微子设施（LBNF）和深层地下中微子实验（DUNE），将研究中微子的性质。帮助更多地解释宇宙如何运作以及物质存在的原因，这项投资是确保英国科学家未来参与国际 DUNE 实验的重要一步。保持其在科学研究领域的世界领先地位，并继续开发新的尖端技术技能。 STFC 将管理英国对国际设施的投资，使英国科学家和工程师有机会在管理和开发中发挥主导作用。 DUNE 远距离探测器LBNF 光束线和相关的 PIP-II 加速器技术，加强了英国与美国 FNAL 的战略合作伙伴关系。英国为 PIP-II 提供关键的 SRF 加速器系统，将显着增强英国多年来已经开发的世界一流技术。达斯伯里实验室的 SRF 技术领域，提供先进的准备和测试基础设施，可以为未来的国家和国际优先项目提供更大规模、更复杂的技术系统，这样的英国交付也将显着提升 STFC 的国际领导地位和水平。作为英国深部地下中微子实验实物贡献 (IKC) 的一部分，STFC 将为费米实验室的新型 PIP-II SRF 直线加速器提供超导射频 (SRF) 腔和组装的低温模块。建立在 ESS 高贝塔腔计划和 HL-LHC 原型低温模块组件所获得的经验的基础上，这两个项目均由英国资助，在达斯伯里实验室完成预计向 FNAL 交付的范围将是增强英国 SRF 加速结构的工业制造能力、采购高纯度铌片和符合 FNAL 规格的 HB650 腔体制造，并使用现有技术验证这些结构的性能。达斯伯里实验室提供 SRF 测试基础设施，一旦测试确认性能符合要求，将使用待配置的新装配基础设施将腔体组装并集成到低温模块中，该基础设施将容纳每个腔体。将准备好 10m 长的低温容器，组装三个 HB650 低温模块，每个模块包含六个 650MHz 高贝塔腔，然后将其运送到 FNAL 进行高功率测试，然后再安装在 PIP-II 加速器上。
