We are living in an exceptional age for discoveries in particle physics with potential for producing step changes in understanding of the composition and structure of the Universe. The research we plan, supported by the equipment requested here, is at the core of these discoveries. A key objective of the UK and international particle physics communities is to upgrade the Large Hadron Collider, ATLAS and CMS experiments, to enable collection of ten times more data than was originally foreseen. This will allow ATLAS to measure properties of the new boson announced in July 2012 to unprecedented precision, to establish firmly whether it is indeed the Higgs boson, and if so whether it has the properties predicted by the Standard Model of Particle Physics. The extra data will also greatly increase the sensitivity of ATLAS to new physics beyond the Standard Model such as Supersymmetry. In order to realize this goal the ATLAS central tracking detector will need to be replaced to enable operation in the harsher radiation conditions expected at the upgraded LHC. This proposal contributes to that goal by seeking equipment to support development of the cooling system required by the new tracking detector and for testing the electronic modules of the tracker. A second recent major advance, by the T2K experiment in 2011, reports evidence for a non-zero third neutrino mixing angle. This unlocks progress to experiments in so-called charge-parity (CP) violation to answer the mystery of why the Universe contains virtually no anti-matter. Our neutrino group will focus on contributing analysis to confirm the results but also, using membership of LBNE, progress key new detector technology towards a next generation long baseline neutrino experiment to see CP violation. Our focus will be with liquid argon technology and our pioneering work on electroluminescence light readout, key also to our on-going work towards an experiment to see if the proton decays, core to understanding Grand Unified Theories of physics. The equipment request for a new liquid argon detector and gas analysis facility is key here, in particular to open participation in a 35 ton prototype experiment at Fermilab. Closely related is our continued participation also in SNO+, aimed at understanding solar neutrinos, and the MICE experiment. The study of muon cooling with MICE is vital for the design and construction of future accelerator projects such as a Neutrino Factory and Muon Collider. These efforts will be facilitated by the requested fast digital oscilloscope. Technological developments have recently led to major improvements in sensitivity of detectors to WIMP dark matter, thought to comprise 90% of the galaxy. Exploiting our pioneering work in background mitigation, directional sensitivity and analysis, our future work will concentrate on the LZ and DRIFT-CYGNUS experiments. The latter aims to determine a definitive galactic signature for recently claimed low mass WIMP events and will see a new experiment installed at the UK's Boulby underground site, DRIFT-IIe. Low background R&D and radon issues have become core to such rare event physics, including searches for rare double beta decay. The proposed Rn adsorption test facility fits well here and is also of interest to the environmental science community and development of the UK's underground Boulby site. All the equipment also supports our generic R&D, closely related to a vigorous knowledge exchange programme. Highlight activity will include development of particle tracking in liquid argon relevant to medical applications, gas-based directional neutron detectors with relevance for homeland security and use of muon detectors to monitor CO2 underground storage, all part of our work on social agendas in climate change and crime prevention. Finally, the requested computational suite crosses all research groups to allow multiple services to run on the same host machine and future-proof the group's computing.

我们生活在颗粒物理学中的发现的特殊时代，可能会在理解宇宙的组成和结构方面产生步骤变化。我们计划的研究得到了这里要求的设备的支持，是这些发现的核心。英国和国际粒子物理社区的一个关键目标是升级大型强子对撞机，地图集和CMS实验，以使收集十倍数据的数据是最初预见的。这将使地图集可以测量2012年7月宣布的新玻色子的性能，以实现前所未有的精度，确定它是否确实是希格斯玻色子，如果是的，是否具有由粒子物理学标准模型预测的属性。除了超对称性等标准模型之外，额外的数据还将大大提高地图集对新物理学的敏感性。为了意识到这一目标，将需要更换Atlas Central跟踪检测器，以便在升级的LHC预期的更严格的辐射条件下进行操作。该提案通过寻求设备来支持新跟踪探测器要求的冷却系统的开发并测试跟踪器的电子模块的开发。 T2K实验在2011年通过T2K实验的第二个重大进展报告了非零第三中微子混合角的证据。这释放了在所谓的电荷 - 差异（CP）违规中的实验，以回答为什么宇宙几乎不包含反物质的谜团。我们的中微子小组将专注于贡献分析以确认结果，但使用LBNE的成员资格，将关键的新探测器技术推向下一代长的基线中微子实验，以查看CP违规。我们的重点将是液体氩技术和我们在电致发光光读数方面的开创性工作，这也是我们正在进行的实验工作的关键，以查看质子是否腐烂，是理解大统一物理学理论的核心。设备请求新的液体氩探测器和气体分析设施在这里至关重要，特别是在Fermilab的35吨原型实验中开放。密切相关的是我们继续参与SNO+，旨在了解太阳中微子和小鼠实验。对小鼠冷却的研究对于未来加速器项目（例如中微子工厂和Muon Collider）的设计和构建至关重要。这些努力将由要求的快速数字示波器促进。 技术的发展最近导致了检测器对wimb暗物质的敏感性的重大改善，该探测器被认为占银河系的90％。利用我们在背景缓解，定向灵敏度和分析中的开创性工作，我们的未来工作将集中在LZ和漂移过程中。后者的目的是为最近声称的低质量WIMP事件确定一个确定的银河签名，并将在英国的Boulby Underground网站Drift-IIE中安装一个新的实验。低背景研发和ra问题已成为这种罕见的事件物理学的核心，包括搜索罕见的双β衰变。拟议的RN吸附测试设施在这里非常适合，并且对环境科学界和英国地下布尔比网站的发展也很感兴趣。所有设备还支持我们的通用研发，这与有力的知识交换计划密切相关。突出显示的活动将包括与医疗应用相关的液体氩气体跟踪，基于气体的定向中子探测器，与国土安全性相关，并使用MUON检测器来监视CO2 Underground Storage，这是我们在气候变化和预防犯罪的社会议程中的所有部分。最后，要求的计算套件跨越了所有研究小组，以允许多个服务在同一台主机上运行，​​并使该小组的计算未来。
