Future X-ray astronomical satellite missions will require a new type of a detector that can distinguish X-rays and charged particle tracks, so as to reduce the background level. In order to realize these demands, we have been developing monolithic active pixel detectors, named “XRPIX,” based on the silicon-on-insulator (SOI) CMOS technology. XRPIX offers high coincidence time resolution (∼50...
The core of this contribution is the digital integration concept, a novel readout scheme for the front-end of 2D pixelated detectors. By using this concept, the XIDER project, an ongoing collaboration between the ESRF and Heidelberg University, aims at implementing a fast high dynamic range detector optimised for high energy scattering and diffraction applications at the upcoming generation...
Gotthard-II is a charge-integrating microstrip detector developed for the European X-ray Free-Electron Laser (EuXFEL) for experiments using hard X-rays of 5 keV – 20 keV. Thanks to its excellent single photon sensitivity, large dynamic range as well as high frame rate of 4.5 MHz in burst mode, its potential scientific applications at the EuXFEL include X-ray absorption/emission spectroscopy,...
Noise magnitude in absorption x-ray tomographic (CT) images is strongly dependent on the detector pixel size and/or the geometrical magnification. For this reason, when constraints in terms of radiation dose or scan time are present, as in clinical or animal studies, high resolution CT imaging at acceptable noise levels is not feasible. In this context, the use of propagation-based...
The framework for control and data processing of hyperspectral cameras, presented at iWoRiD 2018 [1] has been further developed into a flexible general-purpose toolkit for multiple hyperspectral X-ray detector types. We now demonstrate the result of this continued development through a practical application in synchrotron-based nano-imaging, enabled by the toolkit.
The methods originally...
Detectors for applications in the soft X-ray energy range (250–2000 eV) face several challenges like providing a high signal-to-noise ratio, single photon resolution capability, a large dynamic range, fast readout and a high quantum efficiency as well as the requirement for vacuum mechanical setups.
