The proposed research will contribute to the design and construction of detectors that will enable measurements to elucidate the nature of fundamental physics and the universe we live in. Warwick has experience of building detector components, which we seek to expand considerably with the modest investments requested here. The devices we intend to design and build will contribute to three distinct areas of science: precision Higgs, Standard Model and new phenomena searches at the LHC, ILC and FCC; the physics of neutrinos with the T2K, LBNE, HyperK and SuperNEMO experiments and CP violation at the LHC, ILC and FCC. Warwick has invested substantially in this research programme by committing significant lab space, academic/PDRA/student time and, in particular, with the recent appointment of a new physicist engineer and technician. These are experts from a background in both semi-conductor and optical physics. The equipment requested would have: a) a large, immediate, impact on our research programme and, b) open up significant new physics opportunities. All items requested either do not exist across the Warwick Science Faculty or are not available for general use. In more detail:o The Large Hadron Collider was designed to search for the Higgs boson and new exotic forms of matter, motivated by shortcomings of the Standard Model. Now a Higgs boson has been found and the quest continues to understand its exact nature and to search for new phenomena. The laboratory hardware will be used to develop and test new semiconductor devices for the future ATLAS ITk detector. During the current initial stage of ITk assembly, we are establishing ourselves as the leading Quality Assurance and Quality Control group for the ITk silicon strip modules by constructing thermal cycling equipment which requires accurate metrology to understand the effect of heating/cooling. We would use this equipment and expertise in the development of the future International Linear Collider (ILC) and Future Circular Collider (FCC) semiconductor detectors. We will use the requested computing equipment to analyse the data from the experiment. In particular, we will contribute to the precision measurements of the Higgs boson and to searches for new phenomena such as unexpected decays and production mechanisms of the Higgs boson. o Neutrinos are fundamental particles that may hold the key to an understanding of the early Universe. Our experimental neutrino physics programme aims to measure the fundamental properties of the particle by two different approaches: a) by observing neutrinos change (or `oscillate') from one type into another into via neutrino beam experiments operating on very long baselines (up to 1200 km) ; b) observing very rare neutrinoless double-beta decay processes. A common theme running through much of this work is the application of light-detection and readout as a way of reconstructing the kinematics of a neutrino interaction in a detection medium. To support this work we have established an optical laboratory which, in the past delivered light readout R&D for the T2K project and, is currently supporting our work on a light calibration system for the Hyper-K experiment and readout of the photosensor digitisers for the DUNE project. The requested infrastructure items will allow the expansion of our roles in the construction phase of future projects (e.g. DUNE/Hyper-K) and ensure we continue to play a full part in the analysis of data from T2K and DUNE/Hyper-K prototype detectors. o Our group is also active in generic detector development which both underpins the experimental programme outlined above and which spawns opportunities for interdisciplinary R&D with potential industrial spin-offs.

拟议的研究将有助于设计和建造探测器，使测量能够阐明基础物理学和我们生活的宇宙的性质。沃里克有建造探测器组件的经验，我们希望通过这里所要求的适度投资来大大扩展这些组件。我们打算设计和建造的设备将有助于三个不同的科学领域：在LHC，ILC和FCC的精确希格斯，标准模型和新现象搜索;中微子物理与T2 K，LBNE，HyperK和SuperNEMO实验以及LHC，ILC和FCC的CP破坏。沃里克已投入大量在这一研究计划，通过承诺显着的实验室空间，学术/PDRA/学生的时间，特别是最近任命了一名新的物理学家工程师和技术人员。他们都是具有半导体和光学物理背景的专家。所要求的设备将：a）对我们的研究计划产生巨大的、直接的影响，B）开辟重要的新物理学机会。要求的所有项目要么不存在整个沃里克科学学院或不可用于一般用途。大型强子对撞机的设计是为了寻找希格斯玻色子和新的奇异形式的物质，其动机是标准模型的缺陷。现在，希格斯玻色子已经被发现，人们继续探索它的确切性质，并寻找新的现象。实验室硬件将用于开发和测试未来ATLAS ITk探测器的新半导体器件。在目前ITk组装的初始阶段，我们正在通过构建需要精确计量以了解加热/冷却效果的热循环设备，将自己确立为ITk硅条模块的领先质量保证和质量控制团队。我们将利用这些设备和专业知识开发未来的国际直线对撞机（ILC）和未来的圆形对撞机（FCC）半导体探测器。我们将使用所要求的计算设备分析实验数据。特别是，我们将为希格斯玻色子的精确测量做出贡献，并寻找新的现象，如希格斯玻色子的意外衰变和产生机制。中微子是基本粒子，可能是理解早期宇宙的关键。我们的实验中微子物理方案旨在通过两种不同的方法测量粒子的基本性质：a）通过在很长的基线（长达1 200公里）上进行中微子束实验，观察中微子从一种类型到另一种类型的变化（或“振荡”）; B）观察非常罕见的无中微子双β衰变过程。贯穿这项工作的一个共同的主题是应用光探测和读出作为一种方法来重建中微子在探测介质中相互作用的运动学。为了支持这项工作，我们建立了一个光学实验室，该实验室过去曾为T2 K项目提供光读出研发，目前正在为Hyper-K实验的光校准系统和DUNE项目的光电传感器数字化仪的读出提供支持。所要求的基础设施项目将允许我们在未来项目（例如DUNE/Hyper-K）的建设阶段扩大我们的角色，并确保我们继续在T2 K和DUNE/Hyper-K原型探测器的数据分析中发挥全面作用。o我们的小组还积极参与通用探测器的开发，这既是上述实验方案的基础，也是跨学科研发的机会，具有潜在的工业副产品。
