Detector Upgrade for X-ray Diffractometer

该提案旨在获得一种新的面积检测器，以取代UBC化学系结构表征设施中布鲁克粉末X射线衍射仪的现有闪烁计数器。 这个X射线衍射设施主要由化学研究人员使用，但也为校园内其他部门的研究人员提供服务。现有的探测器已使用8年以上，不再满足用户的需求。升级将允许分析弱衍射材料和样品量有限的材料。事实上，新探测器有望将仪器灵敏度提高近200倍，这将大大减少收集时间并提高信噪比。我们正在申请资金用于探测器和计算机升级，以使计算机和软件与新探测器兼容。设备对HQP的培训很重要。所有级别的研究人员-本科生，研究生和博士后-将能够接受该仪器的实践培训，如果它对他们的研究有用。

This proposal is to obtain a new area detector to replace an existing scintillation counter for the Bruker powder X-ray diffractometers in the UBC Department of Chemistry's Structural Characterization Facility. This X-ray diffraction facility is primarily used by researchers within chemistry, but also serves several researchers from other departments across campus. The existing detector is over 8 years old and no longer serves the needs of the users. The upgrade will permit analysis of weakly diffracting materials and materials where there is a limited amount of sample. In fact, the new detector is expected to improve the instrument sensitivity by nearly a factor of 200, which will significantly reduce collection times and improve signal to noise ratios. We are requesting funds for the detector and computer upgrades to make the computers and software compatible with the new detector. The equipment is important for the training of HQP. Researchers at all levels - undergraduate, graduate, and post-doc - will be able to receive hands-on training on the instrument if it is useful for their research.
