Detectors with Microchannel Plates have found niche applications in soft X-ray UV photon detection, where event counting with high spatial and timing resolution is needed. Different types of readouts for these detectors have been developed over the last several decades. The Timepix readout ASIC placed directly below the MCP in the vacuum is one of the possible readout options. The capability...
Hybrid pixel, single-photon counting detectors have been instrumental in advancing measurement techniques at synchrotron facilities. They enable fine slicing of the rotation angle and shutterless data acquisition for protein crystallography. Fast and efficient detectors are also essential for many modern techniques such as ptychography.
Although incredibly successful for hard X-rays, the...
During the last two decades, Hybrid Photon-Counting (HPC) pixel detectors have significantly improved a large number of techniques performed at synchrotron light sources, and in many cases enabled new ones, due to their high frame-rate, dynamic range and stable operations. The impact of HPC detectors has however been limited mainly to the Tender and Hard X-ray range, while the Soft X-ray...
FASXCAM is a monolithic active pixel sensor (MAPS) tailored for high-rate radiation imaging and advanced dosimetry. It was developed and prototypes manufactured using XFAB 180nm SOI technology. The device integrates two identical 32×64 pixel arrays with 60×60 µm² pixels, coupled to parallel 8-bit SAR ADCs for column-wise digitization and detection energy range 2.9 to 21.6 keV. The architecture...
VIXRID (Vertically Integrated X-Ray Intelligent Detector) is a demonstrator for a heterogeneous 3D-integrated X-ray detector. The detector is constructed from three tiers: a sensor tier, an analog signal processing and digitization tier implemented in a 28nm process, and a digital compression tier implemented in a 28nm process. The detector has a pixel size of 100 x 100 μm, and supports...
The Charge Coupled Device (CCD) has been the detector of choice in recent years for Resonant Inelastic X-ray Scattering (RIXS) beamlines. Recent advances using Electron Multiplying CCDs has meant that individual low energy X-rays can be centroided to obtain a spatial resolution of <5 µm. The RIXS application will be outlined and the state of the art results described from XCAM’s RIXSCam which...
