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.

马克·汤姆森教授被选为长基线中微子设施(LBNF)深层地下中微子实验(DUNE)的联合发言人。沙丘/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向南达科他州桑福德地下研究设施(SURF)的沙丘远探测器发射一束强烈的中微子；距离1300公里。沙丘Far探测器被设想为四个巨大的液氮时间投影室(Lar-TPC)，每个室由10,000吨液氮的活动体积组成。Lar-TPC技术提供了中微子相互作用中产生的粒子的3D图像。这项实验旨在发现中微子振荡中的CP破坏，这可以解释在宇宙中观察到的物质超过反物质的现象。它还使人们能够对质子衰变进行强有力的搜索，这是大统一理论中预测的，而且对核心坍塌超新星产生的中微子很敏感。沙丘是一项由近700名科学家参与的重大国际合作(而且还在迅速增长)。FAR探测器的安装计划于2021年进行。
