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以高能加速电子来提供明亮的光束。由此产生的X射线在探索材料的结构、组成和激发方面提供了一个独特的强大工具。新的磁铁和真空技术意味着，存储环现在可以被设计成提供亮度(在指定带宽内每单位固体角度的单位面积的通量)和相干性大大增加的X射线束。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年底完成了其升级方案的最后阶段，即极亮光源(EBS)项目。在EBS升级的同时，XMAS光束线也经历了升级，特别是在X射线源和X射线光学的重新设计方面，这导致可用于实验的X射线的能量范围显著增加。新的X射线源还导致聚焦在样品位置上的X射线束的尺寸减小。这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在复杂的样品环境中探测材料的结构和功能。能力的提升允许在广泛的能量范围内在相同的样品环境中逐个原子地研究相同的小样品体积，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接近的研究。将在技术相关的条件下研究更多的系统。现在可以利用更高的X射线能量来研究复杂样品环境中的埋藏界面，包括与电化学技术有关的固-液界面和与催化有关的固-气界面。XMaS是一种使能工具，它是英国材料科学研究基础设施的重要组成部分，确保英国研究人员能够获得现在和未来最先进的仪器、专业知识和技术。通过提供基本的能力层和独特的能力，XMAS通过在一系列时间和空间长度尺度上实现X射线表征，促进了研究人员领导的研究。此外，通过培训学生和早期职业研究人员，圣诞为更广泛的材料研究基地提供高技能的人才。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部门未来的竞争力、弹性和创造力，该部门依赖于新型功能材料的开发、表征和开发。圣诞节的科学平衡既包括长期以发现为主导的研究，也包括以短期影响为重点的研究，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。
