The photon science detector group at PSI has more than 20 years of experience in the development of hybrid pixel and microstrip detectors. Initially the focus was on single photon counting detectors and then moved to dynamic gain switching detectors for the upcoming XFELs. Our current developments are driven by Athos the low energy branch of SwissFEL and the upgrade to SLS2 of the SLS. In...
XIDyn is a hard X-ray detector that will measure fluxes up to 10$^1$$^2$ photons/mm$^2$/s with >100 kHz continuous frame rate and capture bursts of frames at up to 5.7 MHz. The detector will have 144 x 192 pixels on a 110 $\mu$m designed to operate with CdZnTe detector material and operate at energies of 10 - 100 keV.
The XIDyn ASIC is a two-stage charge cancellation and digitisation...
At NSLS-II we have a program to develop new detectors based on germanium, to satisfy a demand for detectors with better efficiency at higher x-ray energies. These detectors range from few-element devices with individual readout electronics, to 384-element monolithic strip detectors with multichannel ASIC readout. These have found application on NSLS-II beamlines for a range of applications. We...
This contribution will report on a detection system specially designed and developed to fulfil the needs of X-ray Absorption Spectroscopy (XAS) experiments at the XAFS beamline of the ELETTRA synchrotron. It composed of 8 monolithic multipixel arrays of Silicon Drift Detectors (SDDs), each comprising 8 cells (3x3 mm2) fabricated on 450-μm-thick n-type high-purity silicon wafers with a Tungsten...
Abstract: HEPS-BPIX4 is a new engineering generation hybrid pixel detector prototype with 6M pixels with 140um×140um following the previous one with a pixel size of 150um×150um and frame rate up to 1.2kHz at 20-bit dynamic range. The 6M pixel detector is design for the Biological macromolecule experiment station of HEPS(BA beamline), which will be operational by 2025. The BPIX chip, fabricated...
X-ray Absorption Fine Structure spectroscopy (XAFS) is crucial to investigate the electronic and atomic structure of different kinds of samples [1]. The efficacy of this technique, widely deployed at synchrotron facilities, is constrained by the performance limitations of the current generation of Ge detectors. To perform XAFS measurements, energy-resolving detectors capable of handling high...
DESY in Hamburg, operates one of the brightest storage ring (SR) light sources in the world: PETRA III. The upcoming upgrade of the facility to a 4th generation SR, the PETRA IV project, will increase the brilliance by orders of magnitude and put pressure on existing instrumentation, including detectors. In order to take full advantage of the elevated flux, DESY has engaged in the development...
