The performance of the new 52 kHz frame rate Rigaku XSPA‐500k detector was characterized on beamline 8‐ID‐I at the Advanced Photon Source at Argonne for X‐ray photon correlation spectroscopy (XPCS) applications. Due to the large data flow produced by this detector (0.2 PB of data per 24 h of continuous operation), a workflow system was deployed that uses the Advanced Photon Source data‐management (DM) system and high‐performance software to rapidly reduce area‐detector data to multi‐tau and two‐time correlation functions in near real time, providing human‐in‐the‐loop feedback to experimenters. The utility and performance of the workflow system are demonstrated via its application to a variety of small‐angle XPCS measurements acquired from different detectors in different XPCS measurement modalities. The XSPA‐500k detector, the software and the DM workflow system allow for the efficient acquisition and reduction of up to ∼10⁹ area‐detector data frames per day, facilitating the application of XPCS to measuring samples with weak scattering and fast dynamics.

通过数据管理工作流程在500k像素检测器上实现20 µs分辨的高通量X射线光子相关光谱

新型52 kHz帧速Rigaku XSPA-500k检测器的性能在Argonne的Advanced Photon Source的X-射线光子相关光谱（XPCS）应用的光束线8-ID-I上进行了表征。由于此检测器产生的大量数据流（每24小时连续运行0.2 PB数据），因此部署了工作流系统，该系统使用高级光子源数据管理（DM）系统和高性能软件来快速减小面积实时将检测器数据传输到多头和二次关联函数，为实验人员提供人在回路反馈。通过将其应用于从不同XPCS测量方式的不同探测器采集的各种小角度XPCS测量中，可以证明工作流系统的实用性和性能。XSPA‐500k检测器每天^9个区域检测器数据帧，有利于XPCS在测量弱散射和快速动力学的样品中的应用。
