In recent years we have learnt a great deal about the properties of the elusive neutrino from accelerator experiments wherea beam of neutrinos is fired over distances of hundreds of miles and their rare interactions are detected in large deepunderground experiments. As the propagate over large distances neutrinos change flavour and by studying these neutrinooscillations we can learn a lot about their nature. The next generation of long baseline (LBL) neutrino oscillationexperiments will address one of the most crucial questions in particle physics: is CP violated in the neutrino sector? If this isthe case, that it would represent a breakthrough discovery with the potential to explain the matter-antimatter asymmetry inthe Universe through the process called leptogenesis.LBNE is the US flagship next generation neutrino oscillation project. It will send a neutrino beam 1300 km from Fermilabtowards a large Liquid Argon (LAr) detector located in South Dakota. In 2012 LBNE received US DoE CD-1 approval with aprovisional budget of $867M and CD-2/CD-3 approval is expected by 2017, with start of data taking planned for 2023. Thisproposal is for initial bridging funds for 9 months, which will allow the UK to retain and build on existing leadership in thiscrucial period that will see first operations in 2014 of both the LBNE 35 ton prototype detector and the first neutrino beaminteractions in the MicroBooNE detector; these are significant steps towards the full LBNE LAr far detector.

近年来，我们从加速器实验中获得了关于中微子的难以捉摸的中微子的特性的大量知识，中微子的光束在数百英里的距离内被解雇，并且在大型深处实验中检测到了罕见的相互作用。随着大距离中微子的传播改变风味，通过研究这些中性振荡，我们可以学到很多关于它们的性质的知识。下一代长的基线（LBL）中微子振荡脱落将解决粒子物理学中最关键的问题之一：中微子部门是否违反了CP？如果是这种情况，它将代表突破性的发现，并通过称为瘦化的过程来解释宇宙中物质抗逆点的不对称性。它将距离位于南达科他州的大型液体氩（LAR）检测器1300公里发送中微子梁。 2012年，LBNE收到了我们的DOE CD-1批准，预算为8.67亿美元，预计到2017年将获得8.67亿美元，CD-2/CD-3的批准，并且计划开始计划的数据计划于2023年进行。这项产品是为9个月的初始桥接资金，这将使英国能够在这一重要时期内保留和建立在2014年中的最初运营，这两个概念都将在2014年的中基上进行lbne，这两个概念都将在2014年中均可予以lbne the Inteription 35 35 lbne the。微酮检测器中的光束互相；这些是朝着完整的LBNE LAR检测器迈出的重要步骤。
