Detector Upgrade for X-ray Diffractometer

该提案是为了获得一个新的区域探测器，以取代UBC化学系结构表征设施中布鲁克粉末x射线衍射仪现有的闪烁计数器。这个x射线衍射设备主要供化学研究人员使用，但也为校园其他部门的研究人员提供服务。现有的探测器已经使用了8年以上，已经不能满足用户的需求。该升级将允许分析弱衍射材料和样品数量有限的材料。事实上，新的探测器有望将仪器灵敏度提高近200倍，这将大大减少采集时间并提高信噪比。我们要求为探测器和计算机升级提供资金，使计算机和软件与新的探测器兼容。设备是HQP培训的重要组成部分。所有层次的研究人员——本科生、研究生和博士后——如果仪器对他们的研究有用，将能够接受实际操作的培训。

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.
