Dedicated detector developments for X-ray photon science have significantly contributed to the scientific success of new photon sources. With the development of 4th generation storage rings and high repetition rate FELs new, more performant, X-ray cameras are needed. I will present the ongoing detector developments at DESY for PETRA IV. TEMPUS is a system based on the new TimePix-4 chip....
At the latest synchrotron radiation facilities featuring multi-bend achromat (MBA) storage rings, the current state-of-the-art photon-counting detectors are challenged by the intense X-rays impinging upon the detector. The pileup due to the slow in-pixel counting circuitries typically limits the count rate to around a few Mcps/pixel [1] and reduced further for several bunch modes [2]. To...
The XAFS-DET (Work Package 2) of the European LEAPS-INNOV project has undertaken an ambitious research and development program for a new generation of multi-element monolithic germanium detectors best suited for synchrotron applications [XAFS-DET: A new high throughout X-ray spectroscopy detector system developed for synchrotron applications][1]. The detector has a new age sensor...
In preparation of the upcoming upgrade of the SOLEIL synchrotron to a fourth-generation facility [1], the local detector group and the ASIC design group from AGH University, Krakow, are developing a new single photon-counting hybrid pixel detector prototype called UFERI (Ultra-Fast Energy Resolved Imager [2]). It is dedicated to pseudo-Laue diffraction applications in intense, pink beams at...
Design of Pixel Detectors with analog front-end (AFE) that is suitable for amplitude spectroscopy, true event-driven readout, selective, i.e., per pixel, configuration and built-in testability is presented. The target is a pixelated sensors readout application specific integrated circuit (ASIC) based on front-end and backend technologies recently pursued by BNL, which include, for the...
Gallium arsenide is extensively studied for about seven decades as an excellent material for
semiconductor lasers, LEDs, and microwave electronics. GaAs has noticeable advantages over silicon
and Cd(Zn)Te for radiation detectors. Particularly GaAs has higher electron mobility compared to Si
and Cd(Zn)Te; higher average atomic number compared to Si; and lower probability and energy of...
The High Energy X-ray Imaging Technology (HEXITEC) camera system was developed by the Science & Technology Facilities Council (STFC) in the late 2000’s with the aim of delivering fully spectroscopic (colour) X-ray imaging at energies 2 – 200 keV. The original system has a pixel pitch of 250$\mu$m, 80×80 pixels, each with an energy resolution of ~ 800eV running at 10kHz. To correct for sensor...
