Abstract
In recent years, Hybrid Photon Counting (HPC) detectors have been widely used in the field of X-ray measurement. These detectors display no readout noise and provide a large dynamic range, high frame rate, small point spread function and no blurring. By combining these advantages of HPC detectors with high-speed data readout systems, it is possible to realize a high-performance X-ray detection system with single-photon detection and high detection efficiency. One of the most important elements of HPC detectors is their high-speed readout technology. With the latest HPC detector systems, frame rates of about 1000 fps can be easily realized, which is 1–2 orders of magnitude faster than the frame rate of CCDs, which have been mainstream until now. To meet these demands, the X-ray Seamless Pixel Array (XSPA) detector series was developed. XPSA technology is capable of continuous measurements at 56,000 fps and, with the XSPA Burst Mode, it is possible to achieve intermittent measurements at 970,000 fps. The shortest exposure time for a single frame is 48 nanoseconds. This is achieved by the high-performance UFXC32k chip jointly developed with AGH University and a data readout system that can handle high data rates in real time. In this report, we evaluated the basic performance of the XSPA detector.
