论文摘要
沙丘实验是一个未来的长基线中微子振荡实验，旨在测量中微子CP侵入阶段并确定中微子质量层次结构，以及从超新星从低富集物理学到超越标准模型搜索的丰富物理学计划。第一个FAR检测器的基线技术是基于标准的芯片室技术的经过验证的单相水平饮料液体 - 阿贡TPC。对于第二个远探测器，目前正在开发出一种新技术，即所谓的“垂直漂移” TPC：它旨在结合在Cern Neutrino平台上在Protodune低温器中测试的两种技术的优势，这是经过验证的水平饮用单相TPC和雄心勃勃的垂直液体drifter-drileft dul-phase tpce single-single-single-nifter-nifter-nifter-nifter-nifter-nifter-niver-single-nerterly-Single-Single-Single-Single-Single-Single-Singleshipherthemplys，成一个单一的设计，成为单个相似的词汇TPC使用新型的穿孔PCB阳极设计。该设计保持出色的跟踪和量热的性能，同时显着简化了TPC结构的复杂性。本文介绍了垂直漂移TPC的概念，首先提出了小规模的原型和第一个全尺度阳极模块，并概述了未来原型的计划，以及向完整的第二个沙丘远处检测器迈出的下一步。
The DUNE experiment is a future long-baseline neutrino oscillation experiment aiming at measuring the neutrino CP-violating phase and establishing the neutrino mass hierarchy, as well as at a rich physics programme from supernovae over low-energy physics to beyond Standard Model searches. The baseline technology for the first far detector is a proven single-phase horizontal-drift liquid-Argon TPC based on standard wire-chamber technology. For the second far detector, a new technology, the so-called "vertical drift" TPC is currently being developed: It aims at combining the strengths of the two technologies tested in the ProtoDUNE cryostats at the CERN neutrino platform, the proven horizontal-drift single-phase TPC and the ambitious vertical-drift dual-phase TPC, into a single design, a vertical-drift single-phase liquid-Argon TPC using a novel perforated-PCB anode design. This design maintains excellent tracking and calorimetry performance while significantly simplifying the complexity of the TPC construction. This paper introduces the concept of the vertical drift TPC, presents first results from small-scale prototypes and a first full-scale anode module, and outlines the plans for future prototypes and the next steps towards the full second DUNE far detector.
