Abstract X-ray detectors are of pivotal importance for the scientific and technological progress in a wide range medical, industrial, applications. Here, we take advantage printability perovskite-based semiconductors achieve high sensitivity combined with potential an exceptional spatial resolution by our origami-inspired folded perovskite detector. The performance device is reached solely dete...

Abstract The charge-integrating hybrid silicon pixel detector JUNGFRAU has found widespread use at free-electron laser and synchrotron facilities. was designed for with hard X-rays; yet, because of its low noise, high dynamic range, position resolution, scalable size, is interest soft X-ray applications. We discuss improvements the readout chip alterations entrance window back sensor that facil...

A CMOS (complementary metal-oxide semiconductor) flatpanel X-ray detector is a two-dimensional silicon image sensor with a scintillator. We have tested the performance of two types of CMOS detectors in simultaneous small-angle/wideangle X-ray scattering experiments. Both are active-pixel devices that have an amplifier in each pixel. Wide-angle patterns were recorded with the detector just behin...

We report measurements of eeects of 2.1 MeV and 40 MeV protons on Charge Coupled Device X-ray detectors of a type soon to be launched on several astronomical research satellites. We discuss ground performance characterization techniques and compare our measurements to simple models of the detector damage mechanism. We predict detector peformance degradation rates in low-earth orbit. We plan to ...

Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. CT scanners in clinical use today all use energy-integrating detectors, which measure the total incident energy for each measurement interval...

Localized spectroscopy with simultaneous topographic, elemental and magnetic information is presented. A synchrotron X-ray scanning tunneling microscope has been employed for the local study of the X-ray magnetic circular dichroism at the Fe L2,3-edges of a thin iron film grown on Cu(111). Polarization-dependent X-ray absorption spectra have been obtained through a tunneling smart tip that serv...
