Acquisition of a Rotating Anode X-Ray Generator-Based Diffraction System

这是一项为俄亥俄州立大学化学和物理系研究小组共享使用的高亮度旋转阳极型X射线衍射系统的建议。选择的仪器包括一个18kW旋转阳极X射线发生器，一个双镜聚焦系统，一个能够在广角和小角度模式下运行的自制相机，以及一个一维硅二极管阵列X射线探测器。该仪器将由几个应用研究小组共享，包括：生物液晶相变和薄膜表征的动力学和机理(Caffrey)、手性硫磷脂(TSAI)的结构表征(TSAI)、导电聚合物(Epstein)、反胶束中沸石合成(DUTA)、生物大分子的X射线衍射研究(Sundalingam)、和高压下半导体的弹性性质(Sooryakumar)。这些仪器不会在维修的基础上运行。相反，每组的常规用户将接受自我操作的培训。该系统将由化学系的仪器支持小组进行维护和更新。

This is a proposal for the acquisition of a high brilliance, rotating anode-based x-ray diffraction system for shared use by The Ohio State University research groups in the Departments of Chemistry and Physics. The instrumentation of choice includes an 18kW rotating anode x-ray generator, a double mirror focusing system, a home-built camera capable of performing in both wide- and low-angle modes, and a one-dimensional silicon diode array x- ray detector. The instrumentation will be shared among several research groups for applications including: the kinetics and mechanism of biological liquid crystal phase transitions and thin film characterization (Caffrey), structural characterization of chiral thiophospholipids (Tsai), conducting polymers (Epstein), zeolite synthesis in reverse micelles (Dutta), x-ray diffraction studies of biological macromolecules (Sundaralingam), and elastic properties of semiconductors under high pressure (Sooryakumar). The instruments will not be operated on a service basis. Rather, regular users from each group will be trained for self-operation. The system will be maintained and updated by the Department of Chemistry's instrumentation Support Groups.
