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.

这项拟议的研究将有助于探测器的设计和建造，使测量能够阐明基本物理的性质和我们生活的宇宙。华威拥有制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幅扩大这一经验。我们打算设计和制造的设备将为三个不同的科学领域做出贡献：LHC、ILC和FCC的精密希格斯、标准模型和新现象搜索；T2K、LBNE、HyperK和SuperNEMO实验的中微子物理以及LHC、ILC和FCC的CP破坏。沃里克在这项研究计划上投入了大量资金，投入了大量的实验室空间、学术/PDRA/学生时间，特别是最近任命了一名新的物理学家、工程师和技术员。这些都是来自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，以及b)打开重大的新的物理机会。所要求的所有项目要么不存在于华威科学学院，要么不能用于一般用途。更详细地说：o大型强子对撞机是为了寻找希格斯玻色子和新的奇异物质形式而设计的，其动机是标准模型的缺陷。现在，希格斯玻色子已经被发现，这项任务继续了解它的确切性质，并寻找新的现象。实验室硬件将用于为未来的ATLAS ITK探测器开发和测试新的半导体器件。在目前ITK组装的初始阶段，我们正在通过构建需要精确测量以了解加热/冷却效果的热循环设备，将自己确立为ITK硅带模块的领先质量保证和质量控制小组。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)和未来的环形对撞机(FCC)半导体探测器。我们将使用所需的计算设备来分析实验数据。特别是，我们将对希格斯玻色子的精确测量做出贡献，并探索希格斯玻色子的意外衰变和产生机制等新现象。O中微子是基本粒子，可能掌握着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)通过在很长基线(长达1200公里)上运行的中微子束实验，观察中微子从一种类型到另一种类型的变化(或“振荡”)；b)观测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主题是应用光探测和读出，作为重建探测介质中中微子相互作用的运动学的一种方式。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T2K项目提供光读数研发，目前正在支持我们为Hyper-K实验提供光校准系统的工作，以及为沙丘项目读出光电传感器数字化仪的工作。所要求的基础设施项目将扩大我们在未来项目(例如沙丘/Hyper-K)建设阶段的作用，并确保我们继续充分参与分析来自T2K和沙丘/Hyper-K原型探测器的数据。O我们的团队还积极参与仿制药检测器的开发，这既是上述实验计划的基础，也为跨学科研发带来了机会，并可能产生工业副产品。
