Acquisition of an Advanced CCD X-Ray Detection System for the Advanced Polymers Beamline at the National Synchrotron Light Source for Research and Education

9975663 Hsiao该合同将为采购一种先进的X射线CCD探测器提供部分支持，该探测器将用于布鲁克海文国家实验室（BNL）国家同步加速器光源（NSLS）的先进聚合物光束线（APB，X27 C）。 APB现有的面阵探测器系统包括多丝正比计数器（MWPC）探测器和成像板探测器，这两种探测器都不能满足某些时间分辨和原位实验的严格要求，这些实验需要高空间分辨率和高吞吐率（高探测效率和快速读出时间）。 这些实验包括研究骨骼肌的结构-功能关系、合成纤维和生物纤维的变形、复杂聚合物流体系统的流动诱导结晶和流变学/X射线研究。Advanced Polymers Beamline是进行具有基础和实际重要性的聚合物研究以及探索新材料研究机会的理想选择。 该设施对社区的主要好处是，一般用户不需要广泛的同步加速器经验和设备准备来进行尖端实验。 其中一个例子包括最近开发的同时小角和广角X射线散射（SWAXS）技术，用于表征尺寸为1至1000埃的各向同性聚合物的结构变化。 然而，由于缺乏先进的CCD X射线探测器，研究人员无法充分利用APB的独特研究机会。 CCD X射线探测器不仅将为许多正在进行的项目补充现有的区域探测系统（MWPC，成像板），而且还为各向异性系统的动态研究提供了新的研究机会，这些系统正在成为当前材料研究的前沿。该探测器的获得将大大增强研究能力，并使以前没有X射线经验的学术，政府和工业科学家能够进行尖端的X射线实验。

9975663HsiaoThis award will provide partial support for the acquisition of an advanced x-ray CCDdetector to be used in the Advanced Polymers Beamline (the APB, X27C) at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory (BNL). The current area detector systems at the APB include multi-wire proportional counter (MWPC) detectors and imaging plate detectors, both cannot meet the stringent requirements of certain time-resolved and in-situ experiments that need high spatial resolution and high through-put rate (high detection efficiency and fast read-out time). These experiments include the study of structure-function relationship in skeletal muscles, deformation of synthetic and biological fibers, flow-induced crystallization and rheology/x-ray investigation of complex polymeric fluid systems.The Advanced Polymers Beamline is ideal for carrying out polymer studies of fundamental and practical importance, and for exploring new materials research opportunities. The major benefit of this facility to the community is that no extensive synchrotron experience and equipment preparation is required from the general users to carry out cutting-edge experiments. One of such examples includes the recently developed simultaneous small- and wide- angle x-ray scattering (SWAXS) techniques to characterize structural changes of isotropic polymers with dimensions from 1 to 1000 Angstroms. However, the lack of an advanced CCD x-ray detector has prevented investigators from taking full advantage of the unique research opportunities in the APB. The CCD x-ray detector will not only complement the existing area detection systems (MWPC, imaging plate) for many on-going projects, but also offer new research opportunities for dynamic studies of anisotropic systems that are becoming the forefront of current materials studies.%%%The acquisition of this detector will significantly enhance research capabilities, and enable academic, government, and industrial scientists with no previous x-ray experience to carry out cutting-edge x-ray experiments.***
