“…Low-noise current pre-amplifiers (SR750, Standford Research Systems) are located directly below the ionization chambers and are remotely controlled. Fluorescence yield can be measured with 64 silicon drift detectors (SDDs) (Rachevski et al, 2019). The 64-array detector is a completely depleted volume of n-type 450 mm-thick silicon wafer with eight monolithic arrays.…”

“…of concentration. To increase the efficiency and the sensitivity of the beamline fluorescence experiments, a 64-channel SDD has been developed in collaboration with INFN (Italy), Elettra (Italy) and SESAME (Rachevski et al, 2019). The detector has been recently installed at the XAFS/XRF beamline and its performances have been verified.…”

XAFS/XRF is a general-purpose absorption spectroscopy beamline at the Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME), Jordan. Herein, its optical layout is presented along with its powerful capabilities in collecting absorption and fluorescence spectra within a wide energy range (4.7–30 keV). The beamline is equipped with a conventional fixed-exit double-crystal monochromator that allows the collection of an X-ray absorption spectrum within a few minutes in step-by-step mode. An on-the-fly scanning mode will be implemented shortly where the acquisition time will be reduced to less than a minute per scan. The full automation of the beamline allows performing successive measurements under different conditions. The different experimental setups and special features available to users are reported. Examples of XRF and XAFS measurements are presented, showing the performance of the beamline under different standard conditions.

“…The complete detector has a noticeable total area of 12 300 mm 2 , and thanks to a multi-element SDD architecture allows a wide solid angle coverage of 1.57 steradiants around the specimen, that largely increases the detection efficiency with respect to the previously adopted detection system, and measured a best energy resolution of 125 eV FWHM on the 5.9 keV line [8]. The Xray absorption and fine structure (XAFS) detector for SESAME, on the other hand, adopts SIRIO to realize a high-count-rate detection system with 64 channels; the detector is capable of reaching 15.5 Mcps, a significant improvement with respect to commercially available systems for similar applications, and the best performing pixels registered a resolution below 150 eV FWHM on the 5.9 keV at moderate cooling [9]. The achieved results on the TwinMic/XRF and on the SESAME/XAFS detectors realized by the ReDSoX collaboration, have shown that the SIRIO preamplifier is sufficiently mature to be integrated in complex multi-channel applications.…”

The increasing demand for performance improvements in radiation detectors, driven by cutting-edge research in nuclear physics, astrophysics and medical imaging, is causing not only a proliferation in the variety of the radiation sensors, but also a growing necessity of tailored solutions for the front-end readout electronics. Within this work, novel solutions for application specific integrated circuits (ASICs) adopted in high-resolution X and $$\upgamma $$ γ ray spectroscopy applications are studied. In the first part of this work, an ultra-low noise charge sensitive amplifier (CSA) is presented, with specific focus on sub-microsecond filtering, addressing the growing interest in high-luminosity experiments. The CSA demonstrated excellent results with Silicon Drift Detectors (SDDs), and with room temperature Cadmium-Telluride (CdTe) detectors, recording a state-of-the-art noise performance. The integration of the CSA within two full-custom radiation detection instruments realized for the ELETTRA (Trieste, Italy) and SESAME (Allan, Jordan) synchrotrons is also presented. In the second part of this work, an ASIC constellation designed for X-Gamma imaging spectrometer (XGIS) onboard of the THESEUS space mission is described. The presented readout ASIC has a highly customized distributed architecture, and integrates a complete on-chip signal filtering, acquisition and digitization with an ultra-low power consumption.

“…In addition, these detectors have dedicated electronics for each element and thus allow achieving high statistics in a short acquisition time with a very-high count rate. To give an example, using a 0.9 µs peaking time, while conventional SDDs typically afford a maximum output count rate (OCR) of approcimately 100 kcounts/s, a complete multi-element SDD array can result in an OCR as high as 8 Mcounts/s [8], while maximizing the collection solid angle. However, at present, they are not as widespread as expected, due to their high cost.…”

Detectors and Cultural Heritage: The INFN-CHNet Experience

et al. 2021

View full text Add to dashboard Cite

Detectors are a key feature of the contemporary scientific approach to cultural heritage (CH), both for diagnostics and conservation. INFN-CHNet is the network of the Italian National Institute of Nuclear Physics that develops and applies new instrumentation for the study of CH. This process results in both optimized traditional state-of-the-art and highly innovative detection setups for spectrometric techniques. Examples of the former are X-rays, gamma-rays, visible-light and particles spectrometers tailored for CH applications, with optimized performances, reliability, weight, transportability, cost, absorbed power, and complementarity with other techniques. Regarding the latter, examples are ARDESIA, the array of detectors at the DAΦNE-Light facility, the MAXRS detection setup at the Riken-RAL muon beamline and the imaging facilities at the LENA Laboratory. Paths for next-generation instruments have been suggested, as in the case of the X-ray Superconductive Detectors and X-ray Microcalorimeter Spectrometers, allowing astonishing improvement in energy resolution. Many issues in CH can now be addressed thanks to scientific techniques exploiting the existing detectors, while many others are still to be addressed and require the development of new approaches and detectors.
