Synchrotron radiation (SR) sources provide brilliant beams of light by accelerating electrons at high energies around a circular magnetic lattice. The resulting X-rays provide a uniquely powerful tool in the exploration of structure, composition and excitations in materials. XMaS is an integral part of the UK's synchrotron radiation (SR) infrastructure and has been supporting UK materials scientists since it began operations at the European Synchrotron Radiation Facility (ESRF) in 1997. Following the recently completed ESRF upgrade, XMaS has undergone extensive modifications to deliver a state-of-the-art facility fully exploiting the capabilities of the new machine. It delivers a much more brilliant X-ray beam with an operational energy range from 2.1 to 40 keV. The upgraded facility is more versatile, providing a combination of techniques from X-ray diffraction to small angle X-ray scattering as well as X-ray absorption and emission spectroscopy. Due to the close engagement with users in co-developing and refining sample environments the scientific areas addressed on XMaS are broad and interdisciplinary. The science portfolio on XMaS continues to evolve, embracing a broad spectrum of scientific disciplines under the generic theme of materials science, cutting across research in physics, chemistry, biosciences, healthcare, engineering, and energy. XMaS provides access to tender X-ray spectroscopy (2-4 keV), which is very uncommon and in high demand, especially for application to materials such as batteries and catalysts as well as in heritage and environmental research. The new high energy capability (25-40 keV) opens up operando experiments as well as accessing technologically important X-ray absorption edges. The same sample volume is measured across an extensive energy range and within the same sample environment. This enables real time reactions to be followed on a site-by-site basis and help develop new materials to accelerate the delivery of NetZero 2050. Combined X-ray metrologies and simultaneous measurements of sample properties allow the function-structure relationship to be explored across a wide range of length and time scales. It is by building on these new capabilities, that XMaS is able to deliver the correlative characterisation that is needed to understand ever more complex and heterogeneous materials and devices under technologically relevant conditions.XMaS is an enabling tool, and is 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. XMaS provides an essential layer of capacity and unique capabilities. 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 will encompass 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) 源通过在圆形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。 XMaS 是英国同步辐射 (SR) 基础设施的一个组成部分，自 1997 年开始在欧洲同步辐射设施 (ESRF) 运行以来，一直为英国材料科学家提供支持。继最近完成的 ESRF 升级之后，XMaS 进行了广泛的修改，提供最先进的设施，充分利用新机器的功能。它可提供更加明亮的 X 射线束，工作能量范围为 2.1 至 40 keV。升级后的设施更加通用，提供了从 X 射线衍射到小角度 X 射线散射以及 X 射线吸收和发射光谱技术的组合。由于与用户在共同开发和完善样本环境方面的密切合作，XMaS 所涉及的科学领域非常广泛且跨学科。 XMaS 上的科学组合不断发展，涵盖了材料科学这一通用主题下的广泛科学学科，涵盖物理、化学、生物科学、医疗保健、工程和能源领域的研究。 XMaS 提供了对招标 X 射线光谱 (2-4 keV) 的访问，这是非常罕见且需求量很大的，特别是对于电池和催化剂等材料的应用以及遗产和环境研究。新的高能能力（25-40 keV）开启了操作实验以及访问技术上重要的 X 射线吸收边缘。在广泛的能量范围内和相同的样品环境中测量相同的样品体积。这使得能够逐个站点地跟踪实时反应，并帮助开发新材料以加速 NetZero 2050 的交付。结合 X 射线计量和样品特性的同步测量，可以探索跨区域的功能-结构关系。范围广泛的长度和时间尺度。正是通过建立这些新功能，XMaS 能够提供在技术相关条件下了解更加复杂和异构材料和设备所需的相关表征。XMaS 是一种支持工具，是英国的重要组成部分材料科学研究基础设施确保英国研究人员现在和未来都能获得最先进的仪器、专业知识和技术。 XMaS 提供了重要的容量层和独特的功能。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合作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 的科学平衡将涵盖以发现为主导的长期研究以及以影响为重点的短期研究，从而为变革性的、以挑战为主导的材料科学研究提供环境。
