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.

这项建议是为了获得一个新的面积探测器，以取代现有的闪烁计数器，用于不列颠哥伦比亚大学化学系结构表征设施中的布鲁克粉末X射线衍射仪。这种X射线衍射设备主要供化学领域的研究人员使用，但也为校园内其他部门的几名研究人员提供服务。现有的探测器已有8年以上的历史，已不能满足用户的需要。此次升级将允许对弱衍射材料和样品数量有限的材料进行分析。事实上，新探测器有望将仪器灵敏度提高近200倍，这将显著减少采集次数，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的探测器兼容。该设备是HQP培训的重要设备。如果仪器对他们的研究有用，各级研究人员--本科生、研究生和博士后--都将能够接受关于该仪器的实践培训。
