Now is an exceptional 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 endeavor. 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 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. Our involvement in the T2K experiment in Japan also greatly benefited from confirmation of a non-zero third neutrino mixing angle, a result fundamental to our understanding of the neutrino. The group's respected work in neutrino analyses for T2K, particularly of so-called charge current and neutral current events, will also continue. However, here, bolstered by the exciting new results, 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, notably using LBNE/F in the US and Hyper-K in Japan. For these our particular focus will be on detector construction and the requested equipment will be critical to underpinning this. For instance, we plan leading work on the precursor LAr1-ND experiment at Fermilab where we will construct the central Anode Plane Array for the detector. In parallel we need to expand our pioneering liquid argon R&D. The purifier and impurity monitoring apparatus requested will allow us to produce leading results in this area, for instance on the physics of charge transport in liquid argon. This will also allow us to establish novel detector prototypes at the new CERN-based neutrino platform and for LBNE/F itself. 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 step-change in sensitivity to dark matter particles. Supporting our computing hardware will enable us to lead analysis for the EDELWEISS experiment and then lead key simulations for the upcoming LZ experiment in the US. Our pioneering work on detectors with sensitivity to galactic signatures can also be supported this way. This includes the DRIFT direction sensitive experiment at Boulby and the new DM-ICE250 NaI experiment, which US collaborators recently agreed will be hosted at Boubly to seek an annual modulation signal for dark matter. Meanwhile, our generic detector R&D and knowledge exchange programme is vital to underpinning the group's expertise and skills-base. The requested equipment focused on radio-assay of materials is required so that we can maintain leading studies of rare backgrounds that hinder many rare-event experiments, but that also have relevance in industry. For instance radon detection. This can benefit from our historic links to the Boulby deep underground science laboratory. Other areas that can benefit from the capital programme, particularly in the electronics items requested, include our muon tomography projects for climate change, spin-out work on novel motor control electronics and our novel welding technology. The latter requires, in particular, the new state of the art workshop machines requested. Our long-standing efforts to develop liquid argon technology for neutrino physics are also relevant to medical imaging requirements. The data acquisition and analytical instrumentation requested can greatly aid this to complete a new prototype instrument, building on MRC investment, as well for our core neutrino programme.

现在是粒子物理和粒子天体物理学发现的特殊时间。这里提出的设备提案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。它与我们的STFC合并赠款计划请求密切相关。2015-2019期。最近，我们的工作中最重要的是参与了Higgs玻色子粒子的地图集的发现。该小组的成员领导并帮助开发了该发现所基于的主要4-Lepton分析。这项工作将继续进行，但为未来做准备，我们正在寻找的设备对于扩大在Atlas升级计划中的一般角色至关重要，以构建新Atlas Tracker的关键组成部分。我们参与日本的T2K实验也很大得益于确认非零的第三个中微子混合角，这是我们对中微子的理解的基础。该小组在中微子分析T2K方面的尊敬的工作，特别是所谓的电荷电流和中性时事事件，也将继续进行。但是，在这里，受到令人兴奋的新结果的支持，我们的资本要求是让我们参与下一代长的基线中微子中微子实验，以违反CP违规，旨在揭示宇宙中Antermatter的奥秘，尤其是在美国使用LBNE/F，在日本使用LBNE/F。对于这些，我们的特别重点将是探测器构建，所请求的设备对于为此而言至关重要。例如，我们计划在Fermilab的前体LAR1-ND实验上进行领导工作，在那里我们将为检测器构造中央阳极平面阵列。同时，我们需要扩展我们的开创性液体氩气研发。所需的净化器和杂质监测设备将使我们能够在该区域中产生领先的结果，例如液体氩电荷运输物理。这也将使我们能够在新的基于CERN的中微子平台和LBNE/F本身上建立新颖的检测器原型。对于粒子天体物理学，我们计划开发用于检测暗物质的新努力，认为占宇宙的90％。这里有强烈的动力，因为美国Lux实验最近对暗物质颗粒的敏感性产生了逐步变化。支持我们的计算硬件将使我们能够为Edelweiss实验进行分析，然后为美国即将进行的LZ实验进行主要模拟。我们对探测器的开创性工作也可以通过这种方式支持对银河系特征的敏感性。这包括Boulby的漂移方向敏感实验和新的DM-ICE250 NAI实验，美国合作者最近同意将在Boubly托管，以寻求对暗物质的年度调制信号。同时，我们的通用探测器研发和知识交流计划对于支持该小组的专业知识和技能基础至关重要。需要以材料的放射测定为重点的设备，以便我们可以维持对罕见背景的领先研究，从而阻碍许多罕见的事实实验，但这在行业中也具有相关性。例如ra检测。这可以从我们与布尔比深地下科学实验室的历史性联系中受益。可以从资本计划中受益的其他领域，尤其是在所需的电子项目中，包括我们的MUON层析成像项目，用于气候变化，新型电动机控制电子产品的衍生作品和我们的新颖焊接技术。后者尤其要求新的最新研讨会机器要求。我们为中微子物理学开发液体氩技术的长期努力也与医学成像要求有关。所请求的数据采集和分析仪器可以极大地帮助您完成基于MRC投资的新原型工具以及我们的核心中微子计划。
