In recent years we have learnt a great deal about the properties of the elusive neutrino from accelerator experiments where a beam of neutrinos is fired over distances of hundreds of miles and their rare interactions are detected in large deep underground experiments. As the propagate over large distances neutrinos change flavour and by studying these neutrino oscillations we can learn a lot about their nature. The next generation of long baseline (LBL) neutrino oscillation experiments will address one of the most crucial questions in particle physics: is CP violated in the neutrino sector? If this is the case, that it would represent a breakthrough discovery with the potential to explain the matter-antimatter asymmetry in the 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 Fermilab towards a large Liquid Argon (LAr) detector located in South Dakota. In 2012 LBNE received US DoE CD-1 approval with a provisional budget of $867M and CD-2/CD-3 approval is expected by 2017, with start of data taking planned for 2023. This proposal is for initial bridging funds for 9 months, which will allow the UK to retain and build on existing leadership in this crucial period that will see first operations in 2014 of both the LBNE 35 ton prototype detector and the first neutrino beam interactions 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了解了难以捉摸的中微子的特性，在这些实验中，中微子束在数百英里的距离上发射，并且在大型深层地下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，通过研究这些中微子振荡，我们可以学到很多关于它们的性质的知识。下一代长基线（LBL）中微子振荡实验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，它将代表一个突破性的发现，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。它将从费米拉布（Fermilab）派出1300公里的中微子梁向位于南达科他州的大型液体氩探测器（LAR）探测器。 2012年，LBNE收到了我们的DOE CD-1批准，预算为8.67亿美元和CD-2/CD-3批准，预计将于2017年获得批准，并计划在2023年开始使用数据。该提议是为9个月的初始桥接资金而进行的，这将使英国能够在这一至关重要的时期内保持现有领导和建立在2014年的最初运营，并在2014年首次驾驶Entive tection the Lebiption。在微酮检测器中；这些是朝着完整的LBNE LAR检测器迈出的重要步骤。
