Exploiting XMaS Studies of Highly Correlated Electron Systems, Real Surfaces and Biomaterials

为ESRF的英国CRG XMaS的第三个运作期提供资金，该项目为来自大学物理系和化学系的十多个英国研究小组提供具有国际竞争力的基于sr的衍射研究设施。该光束线于1998年向用户开放，由ESRF的5人团队组成，由利物浦（CA Lucas）和沃里克（MJ Cooper）共同指导，迄今为止已连续两次获得EPSRC 5年运营拨款的支持。它以其独特的样品环境和分析设施而闻名，特别是低温高磁场和极化分析，这导致了在磁体，超导体和CMR化合物，稀土和锕系元素多层等高度相关系统中突出的共振x射线衍射工作，建立了电荷顺序和电子结构的细节。此外，来自真实表面的非共振散射范围从量子点到自组织阵列，以及与电催化和文化遗产物体腐蚀有关的电解研究；此外，波束线适应生物材料的各种工作（牙本质的应变，生物组织的散射特征）。该光束线是一个成熟的设施，将与新兴的英国设施DIAMOND合作，后者在英国社区的规模和多样性问题期间无法提供可比的研究设施，以确保通过联合PDRA任命为英国社区提供全面的服务和技术转让。

Funding is requested for a third operational period of the UK CRG XMaS at ESRF, which provides a facility for internationally competitive SR-based diffraction studies for over a dozen UK research groups predominantly from university Physics, and Chemistry departments. The beamline, which opened to users in 1998, is staffed by a team of 5 based at ESRF and co-directed from Liverpool (CA Lucas) and Warwick (MJ Cooper) and has been supported by two successive 5yr EPSRC operational grants to date. It is distinguished by its unique sample environment and analysis facilities, especially low temperature high magnetic field and polarisation analysis which have led to highlighted resonant x-ray diffraction work on in highly correlated systems such as magnets, superconductors and CMR compounds, rare earth and actinide multilayers, establishing details of the charge ordering and the electronic structure. In addition non resonant scattering from real surfaces has ranged from quantum dots to self organised arrays and the study of electrolysis in relationship to electrocatalyis and the corrosion of cultural heritage objects; in addition the beam line accommodates diverse work on biomaterials (strain in dentine, scattering signatures of biological tissue).The beamline, which is a mature facility, will work with the emerging UK facility DIAMOND, which cannot provide comparable research facilities in the period in question for the size and diversity of the UK community, to ensure a comprehensive provision for the UK community and transfer of know-how via a joint PDRA appointment.
