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

ESRF为英国CRG XMAS的第三个运行期申请资金，该机构为主要来自大学物理和化学系的十几个英国研究小组提供了一个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的一个5人团队组成，由利物浦(CA Lucas)和华威(MJ Cooper)共同指导，迄今已连续两次获得EPSRC为期5年的运营拨款。它的独特样品环境和分析设施，特别是低温强磁场和极化分析，导致在高度相关的系统中，如磁体、超导体和CMR化合物、稀土和氡系元素多层膜，进行了突出的共振x射线衍射工作，建立了电荷有序和电子结构的细节。此外，从量子点到自组织阵列的真实表面的非共振散射，以及与电催化和文化遗产物品的腐蚀相关的电解研究；此外，光束线容纳了关于生物材料的各种工作(牙本质中的应变，散射生物组织的特征)。光束线是一个成熟的设施，将与新兴的英国设施钻石合作，后者在所述时期无法为英国社区的规模和多样性提供可比的研究设施，以确保通过PDRA联合任命为英国社区提供全面的供应和转让技术诀窍。

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.
