We live in an amazing time for discoveries in particle physics and particle astrophysics. The equipment proposal made here is designed to support the research we wish to conduct at Sheffield that is at the heart of this endeavour. It is closely associated with our STFC consolidated grant programme request for the period 2015-2019. Foremost amongst our work recently has been involvement in follow-on from the discovery by ATLAS of a Higgs boson particle. Members of the group led and helped to develop the key 4-lepton analysis upon which the discovery was based. This work will continue but, preparing for the future, the equipment we are seeking will be critical to expanding our generic role in the ATLAS upgrade programme to build key components of a new ATLAS tracker. In neutrino physics, bolstered by exciting new results in our understanding of how neutrinos oscillate from one type to another, our capital request is key to allowing us to participate in next generation long baseline neutrino experiments for CP violation, aimed to unravel the mystery of antimatter in the Universe. The DUNE experiment, recently funded in the US to proceed with excavation underground for the first 80 kton liquid argon module, is vital to this as complement to the Hyper-K experiment in Japan. For these our particular focus will be on detector construction and the requested equipment will be critical to underpinning this. For instance, building on our leading work on the precursor SBND experiment at Fermilab, we will now construct the central Anode Plane Array frames for the protoDUNE experiment at CERN. The latter requires, in particular, the new state of the art workshop machine requested. In parallel we need to expand our pioneering liquid argon R&D. The laser system and data acquisition apparatus requested will allow us to produce leading results in this area, specifically on space charge and electron trapping physics that has dogged recent experiments. For particle astrophysics we plan to develop new efforts on detection of dark matter, thought to comprise 90% of the Universe. There is strong motivation here because the US LUX experiment recently produced a new step-change in sensitivity to dark matter particles. Supporting our computing hardware for the LUX-ZEPLIN experiment, the next generation device in which we are involved, will allow us to grow leadership in simulations. Our pioneering work on detectors with sensitivity to galactic signatures can also be supported this way. This includes the new CYGNUS-TPC project now backed by 20 institutes to build a global dark matter telescope. Meanwhile, our generic detector R&D and knowledge exchange programme is vital to underpinning the group's expertise and skills-base. The requested equipment can benefit our historic links to the Boulby deep underground science laboratory and our muon tomography projects for climate change, spin-out work on novel motor control electronics and our novel welding technology ideas. Our long-standing efforts to develop liquid argon technology for neutrino physics are also relevant to medical imaging requirements. The data acquisition and laser instrumentation requested can greatly aid this area as well.

我们生活在一个粒子物理学和粒子天体物理学发现的惊人时代。这里提出的设备建议旨在支持我们希望在谢菲尔德进行的研究，这是这项工作的核心。它与我们2015-2019年期间的STFC综合赠款方案申请密切相关。我们最近的工作中最重要的是参与了ATLAS发现希格斯玻色子粒子的后续工作。该小组的成员领导并帮助开发了该发现所基于的关键4轻子分析。这项工作将继续进行，但为未来做好准备，我们正在寻求的设备对于扩大我们在ATLAS升级计划中的通用作用至关重要，以构建新ATLAS跟踪器的关键组件。在中微子物理学中，我们对中微子如何从一种类型振荡到另一种类型的理解得到了令人兴奋的新结果的支持，我们的资本要求是允许我们参与下一代长基线中微子实验的关键CP破坏，旨在揭开宇宙中反物质的奥秘。最近在美国资助的DUNE实验，为第一个80 kton液态氩模块进行地下挖掘，作为对日本Hyper-K实验的补充，这是至关重要的。为此，我们将特别关注探测器的建造，所要求的设备将是支撑这一点的关键。例如，在费米实验室SBND实验的基础上，我们现在将为CERN的protodUNE实验构建中央阳极平面阵列框架。后者特别需要所要求的最先进的车间机器。与此同时，我们需要扩大我们领先的液氩研发。所要求的激光系统和数据采集设备将使我们能够在这一领域取得领先的成果，特别是在最近的实验中一直困扰着空间电荷和电子捕获物理学方面。对于粒子天体物理学，我们计划在探测暗物质方面做出新的努力，暗物质被认为占宇宙的90%。这里有强烈的动机，因为美国LUX实验最近产生了对暗物质粒子敏感性的新的阶跃变化。为我们参与的下一代设备LUX-ZEPLIN实验支持我们的计算硬件，将使我们能够在模拟方面发挥领导作用。我们在对银河系特征敏感的探测器方面的开创性工作也可以通过这种方式得到支持。这包括新的CYGNUS-TPC项目，该项目目前由20个研究所支持，旨在建立一个全球暗物质望远镜。与此同时，我们的通用检测器研发和知识交流计划对于巩固集团的专业知识和技能基础至关重要。所要求的设备可以使我们与Boulby深层地下科学实验室的历史联系和我们的气候变化μ子断层扫描项目，新型电机控制电子产品的衍生工作以及我们的新型焊接技术理念受益。我们长期致力于为中微子物理学开发液氩技术，这也与医学成像要求有关。所需的数据采集和激光仪器也可以极大地帮助这一领域。
