Bridging Proposal for travel support for DUNE co-spokesperson

马克·汤姆森教授当选为长基线中微子设施（LBNF）深地下中微子实验（DUNE）的联合发言人。DUNE/LBNF将是美国有史以来最大的粒子物理项目。它包括从芝加哥附近的费米实验室发射强烈的中微子束，到南达科他州桑福德地下研究设施（SURF）的DUNE远距探测器；1300公里的距离。DUNE远端探测器被设想为四个巨大的液态氩时间投影室（LAr-TPCs），每个由10,000吨液态氩的活跃体积组成。LAr-TPC技术提供了在中微子相互作用中产生的粒子的3D图像。该实验旨在发现中微子振荡中的CP破坏，这可以解释宇宙中观测到的物质超过反物质的现象。它还可以对大统一理论中预测的质子衰变进行强大的搜索，并且对核心坍缩超新星产生的中微子很敏感。DUNE是一个由近700名科学家组成的大型国际合作项目（并且还在迅速增长）。该探测器计划于2021年安装。

Professor Mark Thomson was elected as co-spokesperson of the Deep Underground Neutrino Experiment (DUNE) at the Long Baseline Neutrino Facility (LBNF). DUNE/LBNF will be the largest particle physics project ever undertaken in the US. It involves firing an intense neutrino beam from Fermilab, near Chicago, to the DUNE far detector in the Sanford Underground Research Facility (SURF) in South Dakota; a distance of 1300 km. The DUNE far detector is conceived as four vast liquid argon time projection chambers (LAr-TPCs), each consisting of an active volume of 10,000 tons of liquid argon. The LAr-TPC technology provides 3D images of the particles produced in neutrino interactions. The experiment aims to discover CP violation in neutrino oscillations, which could explain the observed excess of matter over antimatter in the Universe. It also enables a powerful search for proton decay, which is predicted in Grand Unified theories, and is sensitive to neutrinos from core collapse super-novae. DUNE is a major international collaboration of almost 700 scientists (and rapidly growing). The installation of the far detector is planned for 2021.
