INSTALLATION, COMMISSIONING AND TESTING OF LARGE-AREA DETECTORS FOR MACROMOLECUL

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。作为大分子结晶学中最重要的继续项目之一，束线上的大面积探测器被不断地测试和优化，以达到束线性能。今年，在BL9-2上安装和测试了新的MAR325 CCD探测器，并在该探测器和现有的Quantum-315 CCD探测器上进行了广泛的测试，包括测量和分析数据集，以比较它们的性能。我们收集了大量的Mb数据集，MAR325的性能超过了Quantum-315的CCD探测器。因此，MAR325探测器已永久安装在BL9-2上。此后，在BL1-5上安装和测试了Quantum-315 CCD探测器，取代了更小和更老的Quantum-4探测器，从而显著增强了该光束的数据采集能力

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. As one of the most important continuing projects in macromolecular crystallography, the large-area detectors on the beam lines are continuously tested and optimized to the beam line performance. This year, new MAR325 CCD detector was installed and tested on BL9-2, and extensive tests, including the measurement and analysis of data sets, were performed on this detector and on the existing Quantum-315 CCD detector to compare their performance. Superb Mb data sets were collected and the MAR325 out performed the Quantum-315 CCD detector. The MAR325 detector has accordingly been permanently installed on BL9-2. The Quantum-315 CCD detector was thereafter installed and tested on BL1-5 replacing a smaller and older Quantum-4 detector, thereby providing a significant enhancement to the data acquisition capabilities for this beam
