This bid concerns Supplementary Consumables for use in connection with the Sheffield Particle Physics Programme Consolidated Grant awarded in late 2012. We are living in an exceptional age for discoveries in particle physics and particle astrophysics with potential for producing step changes in understanding of the composition of matter and the structure of the Universe. The research we plan with this consolidated grant in particle physics and particle astrophysics at Sheffield is at the core of these discoveries. Firstly, we appear to be near answering the fundamental question of what gives particles mass. In this field Sheffield will continue to play a leading role in the ATLAS experiment that now looks to be on the verge of solving the mystery by detecting the famous Higgs Boson. Our ATLAS work, where we are currently the only UK group heavily involved in the flagship 4-lepton channel Higgs search, will aim to confirm the first evidence for excess reported in Dec. 2011. Simultaneously work will continue in the equally fundamental hunt to find supersymmetric particles and on radiation modeling and detector tests for the ATLAS upgrade anticipated as the next experiment. We currently provide the UK spokesman for ATLAS.A second recent major advance, made by the T2K experiment in 2011, reports evidence for a non-zero third neutrino mixing angle. This potentially unlocks progress to experiments in so-called charge-parity (CP) violation to answer the mystery of why the Universe contains matter and virtually no anti-matter. Our T2K and neutrino group will focus on contributing further analysis to confirm the new results but also, using our membership of the LBNO and LBNE collaborations, progress key new detector technology towards a next generation long baseline neutrino experiment to see CP violation. For this our focus will be with liquid argon technology, our pioneering work on electroluminescence light readout for that, and our simulation work on backgrounds from muons. The latter is key also to our on-going work towards an experiment to see if the proton decays, an issue at the core of understanding Grand Unified Theories of physics. Closely related and vital for our neutrino programme is continued participation in SNO+, aimed at understanding solar neutrinos, and the MICE experiment with its related R&D on high power particle beam targets for future neutrino beams.Technological developments recently led to significant improvement in sensitivity of detectors to WIMP dark matter with key contributions from the Sheffield group towards EDELWEISS and DRIFT. Exploiting our leadership in background mitigation strategy, calibration and data analysis, our future work will concentrate on EDELWEISS operation and data analysis, as well as on developments towards ton-scale cryogenic experiment EURECA. The group is also uniquely well positioned to contribute through new work aiming to see, or exclude, a definitive galactic signature for the claimed low mass WIMP events. Our pioneering work on directional WIMP detectors will see a new experiment installed at the UK's Boulby underground site, DRIFTIIe, while our continued analysis of data from DM-ICE17 at the Antarctic South Pole, for which we supplied the NaI detectors, will seek an annual modulation galactic signature and inform design of a new experiment there planned for 2013.

这种出价涉及与Sheffield粒子物理计划合并于2012年底授予的补助金有关的补充消耗品。我们生活在粒子物理和粒子天体物理学中发现的特殊时代，具有对物质组成和宇宙结构的理解的潜力变化。我们在谢菲尔德（Sheffield）在粒子物理学和粒子天体物理学中计划的研究是这些发现的核心。首先，我们似乎几乎回答了什么赋予颗粒质量的基本问题。在这个领域，谢菲尔德将继续在Atlas实验中扮演领导角色，现在看来，通过发现著名的希格斯玻色子来解决这个谜团。我们目前是唯一参与旗舰4-Lepton频道Higgs搜索的英国小组的Atlas工作，旨在确认2011年12月报告的第一个过多的证据。同时进行的工作将继续进行，以进行同样的基本狩猎，以寻找超对称颗粒，并在散热器建模和探测器测试中进行了预期的Atlas Upgrade Everectiment。目前，我们为阿特拉斯（Atlas）提供了英国发言人。T2K实验在2011年取得的第二次重大进展，报告了非零第三个中微子混合角的证据。这有可能解锁所谓的指控 - 违规（CP）的实验，以回答为什么宇宙包含重要的事情，几乎没有反物质的谜团。我们的T2K和中微子小组将着重于进一步的分析，以确认新的结果，同时还使用我们对LBNO和LBNE合作的成员资格，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。为此，我们的重点是液体氩技术，我们在电致发光光读数方面的开创性工作，以及我们在Muons背景上的模拟工作。后者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，这是理解大统一物理学理论的核心。与我们的中微子计划密切相关和至关重要，继续参与SNO+，旨在理解太阳中微子，而小鼠实验了其相关的R＆D在高功率粒子光束目标上的相关研发目标，以实现未来的中微子束。技术发展最近导致了检测器对探测器的敏感性的显着提高，从而使探测器的敏感性与Sheffielfield Group to Edelweiss and Driver的关键贡献。利用我们在背景缓解策略，校准和数据分析中的领导力，我们的未来工作将集中于Edelweiss的操作和数据分析，以及对吨量表低温实验Eureca的发展。该小组还具有独特的位置，可以通过新的工作来贡献，以查看或排除为声称的低质量WIMP事件的确定银河签名。我们在定向wimp探测器上的开创性工作将在英国的布尔比地下站点Driftiie上安装一个新的实验，而我们对南极南极DM-ICE17的数据的持续分析继续分析，我们为此提供了NAI探测器，将寻求年度调制的银河系标志，并为2013年的新实验提供了一个新的实验设计。
