Synchrotron radiation (SR) sources provide brilliant beams of light by accelerating electrons at high energies around a magnetic lattice. The resulting X-rays provide a uniquely powerful tool in the exploration of structure, composition and excitations in materials. New magnets and vacuum technologies mean that storage rings can now be designed to give X-ray beams with hugely increased brilliance (flux per unit area per unit solid angle in a specified bandwidth) and coherence. The XMaS (X-ray Materials Science) beamline facility is part of the European Synchrotron Radiation Facility (ESRF) which, in late 2020, completed the final phase of its upgrade programme, the extremely bright source (EBS) project. In parallel with the EBS upgrade, the XMaS beamline also went through an upgrade particularly in the redesign of the X-ray source and X-ray optics which led to a significant increase in the energy range of the X-rays that can be used for experiments. The new X-ray source also led to a decrease in the size of the X-ray beam that is focussed onto the sample position. The result of this upgrade means that experiments can now be performed with outstanding spatial and temporal resolution opening up new possibilities across a range of X-ray methodologies which can be simultaneously applied to probe the structure and function of materials in complex sample environments. The uplift in capability allows the study of the same small sample volume across an extensive energy range and within the same sample environment on an atomic site-by-site basis, opening up new opportunities for studying materials relevant to catalysis and green chemistry applications. The facility will deliver new insights into healthcare and quantum critical behaviour as well as facilitating studies of confinement and proximity in real devices. More systems will be studied operando and under technologically relevant conditions. The higher X-ray energies now available allow studies of buried interfaces in complex sample environments including solid-liquid interfaces relevant to electrochemical technologies and solid-gas interfaces relevant to catalysis. The equipment requested in this proposal is specifically targeted to support these areas of research.XMaS is an enabling tool, and provides an essential part of the UK research infrastructure for material science ensuring that UK researchers have access to state-of-the-art instrumentation, expertise and techniques now and into the future. By providing an essential layer of capacity and unique capabilities, XMaS facilitates investigator-led research by enabling X-ray characterisation across a range of temporal and spatial length scales. In addition, by training students and early career researchers, XMaS provides highly skilled individuals to the wider materials research base. Partnerships with national research centres and international collaborators ensure the future competitiveness, resilience and creativity of the UK materials sector which relies on the development, characterisation and exploitation of novel functional materials. The balance of science on XMaS encompasses both long-term discovery-led research as well as shorter term impact-focused research thereby providing an environment for transformative, challenge-led material science research.

同步辐射 (SR) 源通过在磁晶格周围加速高能电子来提供明亮的光束。由此产生的 X 射线为探索材料的结构、成分和激发提供了独特的强大工具。新的磁体和真空技术意味着存储环现在可以设计成大大提高X射线束的亮度（指定带宽内每单位立体角的单位面积通量）和相干性。 XMaS（X 射线材料科学）光束线设施是欧洲同步辐射设施 (ESRF) 的一部分，该设施于 2020 年底完成了升级计划的最后阶段，即极亮光源 (EBS) 项目。在 EBS 升级的同时，XMaS 光束线也进行了升级，特别是 X 射线源和 X 射线光学器件的重新设计，这导致可用于 X 射线的能量范围显着增加。实验。新的 X 射线源还导致聚焦到样本位置的 X 射线束的尺寸减小。此次升级的结果意味着现在可以以出色的空间和时间分辨率进行实验，为一系列 X 射线方法开辟了新的可能性，这些方法可以同时应用于探测复杂样品环境中材料的结构和功能。能力的提升使得能够在广泛的能量范围内、在相同的样品环境下逐个位点地研究相同的小样品量，为研究与催化和绿色化学应用相关的材料开辟了新的机会。该设施将为医疗保健和量子关键行为提供新的见解，并促进对真实设备中的限制和邻近性的研究。将在操作和技术相关条件下研究更多系统。现在可用的更高 X 射线能量允许研究复杂样品环境中的埋藏界面，包括与电化学技术相关的固-液界面和与催化相关的固-气界面。本提案中要求的设备专门用于支持这些研究领域。XMaS 是一种支持工具，为英国材料科学研究基础设施提供了重要组成部分，确保英国研究人员能够获得最先进的仪器、现在和未来的专业知识和技术。通过提供重要的容量层和独特的功能，XMaS 能够在一系列时间和空间长度尺度上进行 X 射线表征，从而促进研究者主导的研究。此外，通过培训学生和早期职业研究人员，XMaS 为更广泛的材料研究基础提供高技能人才。与国家研究中心和国际合作者的伙伴关系确保了英国材料行业未来的竞争力、弹性和创造力，该行业依赖于新型功能材料的开发、表征和利用。 XMaS 的科学平衡既包括以发现为主导的长期研究，也包括以影响为中心的短期研究，从而为变革性的、以挑战为主导的材料科学研究提供了一个环境。
