This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The goal of this works is to develop brighter, higher resolution scintilators that could improve the performance, and reduce the cost, of detectors designed for structural biology applications. The development is funded by a variety of SBIR grants from NIH and DOE but the testing of them under real beam conditions at 18ID is part of core project I in the BioCAT P41 grant. Currently we are examining films made of CsI:Tl,Sm, structured ZnTe:Om, and a structured ZnSe:Te as possible candidates for high brightness, high spatial resolution scintillators with fast decay times. The most promising of these so far is ZnSe:Te with 180% of the brightness of commercial MinR-2000 screens commonly used for these applications. These have been tested on 18ID with EMCCD and intensified CCD cameras to assess their suitability for the construction of time-resolved scattering detectors. Results of these experiments have been submitted for publication in NIM A. We will soon take delivery of an intensified CMOS camera capable of 3600 fps that we will ultimately be developed into a detector system (70 x 70 mm active area, ~67 micron pixels) when we have found a suitable scintillator. When this arrives we will be using this camera for the scintillator testing program because of it superiority over the EMCCD device.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 这项工作的目标是开发更明亮，更高分辨率的闪烁器，可以提高性能，降低成本，为结构生物学应用设计的检测器。该开发由NIH和DOE的各种SBIR赠款，但在18 ID的真实的光束条件下对其进行测试是BioCAT P41资助的核心项目I的一部分。 目前，我们正在研究由CsI：Tl，Sm，结构化ZnTe：Om和结构化ZnSe：Te制成的薄膜，作为高亮度，高空间分辨率，具有快速衰减时间的发光器件的可能候选物。 到目前为止，其中最有前途的是ZnSe：Te，其亮度为通常用于这些应用的商业MinR-2000屏幕的180%。 这些已被测试18 ID与EMCCD和增强CCD相机，以评估其适用于建设的时间分辨散射探测器。 这些实验的结果已提交给NIM A发表。我们将很快收到一台能够达到3600 fps的增强型CMOS相机，当我们找到合适的闪烁体时，我们将最终开发成探测器系统（70 x 70 mm有效面积，约67微米像素）。 当它到达时，我们将使用这种相机的闪烁体测试程序，因为它优于EMCCD设备。
