This award from the Instrumentation for Materials Research Program to Cornell University will allow several teams of investigators to develop x-ray diffraction instrumentation that will provide unique experimental capabilities and powerful general use equipment for use at the G2 experimental station at the Cornell High Energy Synchrotron Source (CHESS). A six-circle diffractometer, two CCD area detectors, and a temperature- and environment-controlled sample stage will be built. The diffractometer will allow for a very wide range of experimental configurations and will be the basic diffractometer for the G2 experimental station. The area detectors will be used at G2 for a variety of different experiments, but will also be made available to users at other experimental stations easing a current very high over demand for such detectors at CHESS and at Cornell. The stage will be able to hold samples at any temperature between 20 and 900 degrees C in a range of atmospheres during diffraction experiments and will also be used at different experimental stations. Together, this equipment will be optimized for high resolution and time-sensitive x-ray diffraction work. Initial work includes: 1) studies of mechanical deformation, relaxation, and anelastic recovery, as well as interactions among microstructure development, phase changes, and solid state reactions in thin films and nanopattened structures, 2) studies of the evolution of strain and magnetic and electronic properties as a function of controlled oxidation in magnetic oxide thin films and nanostructures, 3) studies of formation and structure of highly ordered arrays by metal initiated self-assembly of ligand modified den-drimers, and 4) studies of the kinetics of interface growth of metal mono- and multilayers. This equipment will be made available to outside users and to students, and will be used in outreach programs such as the Research Experiences for Teachers (RET) and Research Experiences for Undergraduates (REU) programs sponsored by NSF through the Cornell Center for Materials Research (CCMR).%%%This award from the Instrumentation for Materials Research Program to Cornell University will allow several teams of investigators to develop x-ray diffraction instrumentation that will provide unique experimental capabilities and powerful general use equipment for use at the G2 experimental station at the Cornell High Energy Synchrotron Source (CHESS). This equipment will be optimized for high resolution and time-sensitive x-ray diffraction work. It will be used to obtain rapid high resolution measurements of thermally induced phenomena in nanostructured materials, including strain, deformation, phase transformations, magnetic and electronic properties, film formation, and solid state reactions. This equipment will benefit a large number of research groups at Cornell, and also external US and international collaborators. It will be made available to outside users, to students, and will be used in outreach programs such as the very successful Research Experiences for Teachers (RET) and Research Experiences for Undergraduates (REU) programs sponsored by NSF through the Cornell Center for Materials Research (CCMR).

该奖项从材料研究计划到康奈尔大学的奖项将允许几个研究人员开发X射线衍射仪器，该工具将提供独特的实验能力和强大的一般使用设备，可在康奈尔高能同步器源（Chess）的G2实验站使用。将建立一个六圈衍射仪，两个CCD区域探测器以及一个温度和环境控制的样品阶段。衍射仪将允许非常广泛的实验构型，并且将成为G2实验站的基本衍射仪。该区域探测器将在G2上用于各种不同的实验，但也将向其他实验站的用户提供，从而缓解了当前对此类探测器在国际象棋和康奈尔的需求的很高的需求。该阶段将能够在衍射实验期间在一系列大气中在20至900度C之间的任何温度中保存样品，并且在不同的实验站也将使用。共同将该设备用于高分辨率和时间敏感的X射线衍射工作。最初的工作包括：1）研究机械变形，放松和无弹性恢复的研究，以及微结构发展，相变，相变和固态反应的薄膜和纳米齿结构的固态反应，2）磁性氧化膜和nanostruction nanostruction nanostripertion nanostried and Inderation和Nananopathert of nounture of nounture of Melectation和Nananopation的函数的应变和磁性能的演变的研究，3）配体修饰的DEN-DRIMERS，以及4）研究金属单层和多层界面生长动力学的研究。 This equipment will be made available to outside users and to students, and will be used in outreach programs such as the Research Experiences for Teachers (RET) and Research Experiences for Undergraduates (REU) programs sponsored by NSF through the Cornell Center for Materials Research (CCMR).%%%This award from the Instrumentation for Materials Research Program to Cornell University will allow several teams of investigators to develop x-ray diffraction instrumentation that will provide unique experimental capabilities and powerful general use在康奈尔高能同步源（Chess）的G2实验站使用的设备。该设备将通过高分辨率和时间敏感的X射线衍射工作进行优化。它将用于获得纳米结构材料中热诱导现象的快速高分辨率测量，包括应变，变形，相变，磁性和电子特性，膜形成和固态反应。该设备将使康奈尔大学以及美国外部和国际合作者的大量研究小组受益。它将向外部用户（学生）提供，并将用于外展计划，例如由NSF通过康奈尔（Cornell）材料研究中心（CCMR）赞助的本科生（REU）计划的非常成功的研究经验（RET）和研究经验。
