9724501 Parise This grant, made through the Major Research Instrumentation (MRI) Program, provides $295,518 as one-half support of the costs of acquiring equipment for development of a modular, CCD detector-based x-ray diffraction facility that will be used in conjunction with both synchrotron x-ray sources at the National Synchrotron Light Source (NSLS), Brookhaven National Lab (BNL), the Advanced Photon Source (APS), Argonne National Lab (ANL) and laboratory x-ray sources. Specifically, the equipment will include two CCD detector systems allowing real time x-ray diffraction studies of very small single crystals and powdered samples, a significant advantage over more conventional image plate-based XRD systems. One of the CCD detector systems will be used in conjunction with a refurbished Rigaku 18 kW rotating anode that will incorporate focusing mirrors to provide an extra beam and a high brightness focused beam for further in-house development of the T-cup high pressure device originally designed by researchers at the Mineral Physics Institute at SUNY-SB (a node of the CHiPR STC). This modular system will also be transferable to brighter x-ray sources at NSLS and APS for studies of the smallest crystals (0.5 - 20 microns). A second system will alleviate demand for beam time at NSLS by the many postdoctoral, graduate and undergraduate students affiliated with the CHiPR STC who require XRD analyses on crystals ranging in sizes from 20-100 microns for which current laboratory x-ray sources and XRD detector systems are not adequate. Additional funds will be used to purchase a workstation and mass storage for analysis of the high resolution diffraction data and ancillary equipment needed to manufacture this integrated modular system. Specific examples of the cutting edge and funded research that will be enhanced or enabled by this equipment include, development of the next-generation, portable, large volume high pressure cell, determination of the strength and rheological properties of ceramics, textural analysis during ultrasonic experiments for determination of seismic velocities through high pressure phases, structural analyses of organic-inorganic open framework compounds, powder diffraction studies of doped-fullerenes, solid-state organic geochemistry, characterization of low temperature compounds formed during early diagenesis in marine sediments and bio- medical studies of photochemically formed natural compounds. ***

小行星9724501 这项赠款，通过主要研究仪器（MRI）计划，提供295，518美元作为一半的支持购买设备的成本，用于开发一个模块化的，基于CCD探测器的X射线衍射设施，将与国家同步加速器光源（NSLS），布鲁克海文国家实验室（BNL）的同步加速器X射线源一起使用，先进光子源（APS）、阿贡国家实验室（ANL）和实验室X射线源。 具体而言，该设备将包括两个CCD检测器系统，允许对非常小的单晶和粉末样品进行真实的时间X射线衍射研究，这是比更传统的基于图像板的XRD系统更大的优势。其中一个CCD探测器系统将与理学翻新的18 kW旋转阳极结合使用，该阳极将包含聚焦镜，以提供额外的光束和高亮度聚焦光束，用于进一步内部开发T杯高压设备，该设备最初由SUNY-SB矿物物理研究所的研究人员设计（CHiPR STC的一个节点）。该模块化系统还可转移到NSLS和APS的更亮的X射线源上，用于研究最小的晶体（0.5 - 20微米）。 第二个系统将减轻许多隶属于CHiPR STC的博士后，研究生和本科生对NSLS的束流时间的需求，这些学生需要对尺寸从20-100微米的晶体进行XRD分析，目前的实验室X射线源和XRD检测器系统不足以满足这些需求。 额外的资金将用于购买一个工作站和大容量存储器，用于分析高分辨率衍射数据和制造这种集成模块系统所需的辅助设备。 该设备将增强或实现的尖端和资助研究的具体示例包括，下一代便携式大容量高压电池的开发，强度的确定以及 陶瓷的流变学性质，在超声波实验中用于测定通过高压相的地震速度的结构分析，有机-无机开放骨架化合物的结构分析，掺杂富勒烯的粉末衍射研究，固态有机地球化学，海洋沉积物中早期成岩作用形成的低温化合物的表征以及光化学形成的天然化合物的生物医学研究。 ***
