摘要： JUNGFRAU is the pixel detector developed at PSI for SwissFEL. Although the detector development was driven by the SwissFEL requirements, it was soon realized that such a detector could also be of interest for synchrotron light source applications since it would, when operated at high frame rates, significantly extend the count rate capabilities of current-generation single photon counting detectors. In this article, we begin with a basic description of the detector working principle, together with a summary of the detector characterization results. Next, we describe the different JUNGFRAU detector configurations available and their geometries, followed by a description of the detector deployment and operation at SwissFEL. Then, the challenges of using a charge integrating detector at synchrotron light sources are explained, followed by a few examples of the possibilities opened by this kind of detector in such an environment. The last section offers an outlook for the project.
