We apply for an innovative instrument package for the Institute of Geography at the University of Cologne (UoC), which shall be used to develop cutting-edge luminescence tomographies. As main device a new generation luminescence reader will be purchased, which is tailored to InfraRed PhotoLuminescence (IRPL, Prasad et al. 2017; Kumar et al. 2018) and enables spatially resolved luminescence imaging (e.g. HR-IRPL, EMCCD). With the help of IRPL, we can read for the first time dosimetric luminescence information from natural minerals non-destructively. In addition to more specific methodological investigations, this allows improved luminescence analyses of rock surfaces, saprolitic or volcanic materials. These investigations will form the basis for the full development of spatially resolved techniques (especially HR-IRPL, Sellwood et al. 2019). As an associated device to the new generation luminescence reader, we apply for a micro-XRF spectrometer, which shall be used to spatially map element distributions of rock or soil surfaces. Both devices will be installed in the laboratories of the Institute of Geography of the UoC. Internal and external users from the Geoscience Department in Cologne and the Geoverbund ABC/J will also have access to the luminescence tomography instrument package. This innovative instrument package will enable us to record the luminescence properties of mineral grains in their spatial context (luminescence instrument) and to merge this information with elemental distribution maps (micro-XRF). Initially, our luminescence group will develop the methodological basis for IRPL and luminescence imaging. The aim of the methodical investigations is to enable luminescence tomography with the purpose to decode relevant rock, sediment and soil structures in three spatial dimensions and time. Besides spatially resolved numerical age sequences, we can use these novel data to extract contextual and/or process information regarding soil-landscape dynamics or archaeological artifacts. This will enable the applicant and his team to develop highly innovative geoscientific and archaeological applications in close cooperation with the co-applicants.This application extends and strengthens the internationally visible Cologne Luminescence Laboratory (CLL) and thus the geochronological focus at the UoC. The integration of different co-users from the field of Geosciences and Archaeology not only shows the great demand but also the great potential to initiate the develop of highly innovative applications. This will result in excellent networking opportunities and synergies within the Department of Geosciences (UoC), the Geoverbund ABC/J and the Institute of Pre- and Ancient History (UoC). To the best of our knowledge, this instrument package is unique in Central Europe and will contribute to the further strengthen the position of the UoC as an excellent geoscientific research location.

我们为科隆大学(UOC)地理研究所申请了一套创新的仪器，用于开发尖端的发光层析成像。作为主要设备，将购买新一代发光读取器，它是为红外光致发光(IRPL，Prasad等人)量身定做的。2017年；Kumar等人。2018)，并实现空间分辨发光成像(例如，HR-IRPL、EMCCD)。在IRPL的帮助下，我们首次能够无损地读取天然矿物的剂量发光信息。除了更具体的方法研究外，这还可以改进岩石表面、腐殖质或火山物质的发光分析。这些研究将为充分开发空间分辨技术(特别是HR-IRPL，Sellwood等人)奠定基础。2019年)。作为新一代发光阅读器的配套设备，我们申请了微型XRF光谱仪，用于绘制岩石或土壤表面元素分布的空间图谱。这两个设备都将安装在加州大学地理研究所的实验室中。科隆地球科学部和ABC/J地球科学部的内部和外部用户也将可以使用发光层析成套仪器。这一创新的仪器组合将使我们能够记录矿物颗粒在其空间背景下的发光特性(发光仪器)，并将这些信息与元素分布图(微型XRF)合并。首先，我们的发光小组将开发IRPL和发光成像的方法学基础。这些方法研究的目的是使发光层析成像能够在三个空间维度和时间上解码相关的岩石、沉积物和土壤结构。除了空间解析的数字年龄序列，我们还可以使用这些新数据来提取关于土壤-景观动态或考古文物的上下文和/或过程信息。这将使申请者和他的团队能够与共同申请者密切合作，开发高度创新的地球科学和考古应用程序。这一应用程序扩展和加强了国际上可见的科隆发光实验室(CLL)，从而加强了科隆大学的地质年代学重点。来自地学和考古领域的不同共同用户的集成不仅显示了启动高创新应用开发的巨大需求，也显示了巨大的潜力。这将在地球科学系(UOC)、ABC/J地球外滩研究所和古代史研究所(UOC)内部带来极好的联网机会和协同作用。据我们所知，这套仪器在中欧是独一无二的，将有助于进一步加强加州大学作为一个优秀的地球科学研究地点的地位。
