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

资金要求在ESRF的英国CRG XMaS的第三个运行期，它提供了一个具有国际竞争力的基于SR的衍射研究的设施，主要来自大学物理和化学系的十几个英国研究小组。光束线于1998年向用户开放，由ESRF的5人团队组成，并由利物浦（CA Lucas）和沃里克（MJ库珀）共同指导，迄今为止已获得连续两次5年EPSRC运营赠款的支持。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，这导致了高度相关系统中突出的共振X射线衍射工作，如磁体，超导体和CMR化合物，稀土和锕系元素多层膜，建立电荷有序和电子结构的细节。此外，来自真实的表面的非共振散射的范围从量子点到自组织阵列，以及与电催化和文化遗产物品腐蚀有关的电解研究;此外，光束线还可用于生物材料的各种工作（牙本质中的应变，生物组织的散射特征）。光束线是一个成熟的设施，将与新兴的英国设施DIAMOND，在有关时期内无法提供与联合王国社区规模和多样性相当的研究设施，以确保通过联合PDRA任命为联合王国社区提供全面的服务和转让专门知识。

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.
