Intense research activities have been made in the development of room temperature spectroscopic imagers working in the X-ray and gamma ray energy band. Cadmium-zinc-telluride (CZT) detectors equipped with custom electrode structures have shown interesting performance up to 1 MeV, competing with the superb energy resolutions of high-purity germanium (HPGe) detectors (0.3 % FWHM at 662 keV),...
The X-ray diagnostics is an insightful technique to monitor the emission of magnetically confined plasmas. In the PANDORA (Plasmas for Astrophysics, Nuclear decay Observation and Radiation for Archaeometry) INFN project [1] framework, we here present the newly developed energy-space-time resolved diagnostic tool, consisting of a 400 μm lead pinhole coupled with a 4 MP X-ray CCD camera...
Bragg spectroscopy is a consolidated experimental method for high-energy resolution X-ray measurements. However, this technique is limited to the detection of photons produced from point-like or well collimated sources and becomes quite inefficient for photons generated in extended and diffused ones. Also, the possibility to perform simultaneous measurements of several X-ray lines is of great...
Detector performance often hinders the efficiency of advanced synchrotron-based techniques such as X-ray Absorption Fine Structure (XAFS) spectroscopy measured in fluorescence mode, which is essential for probing the electronic structure and elemental composition. To overcome these limitations, the XAFS-DET WP of the European LEAPS-INNOV project has developed a monolithic multielement...
X-ray multimodal imaging is based on the retrieval of phase changes and ultra-small angle scattering (or dark-field) in addition to conventional transmission. The availability of these additional contrast channels has already proven to be valuable in many research fields, including medicine and materials sciences, thanks to the ability to provide superior contrast for soft tissues as well as...
The SIDDHARTA-2 experiment at the DAΦNE collider aims to perform high-precision X-ray spectroscopy of exotic atoms to study the low-energy strong interaction in the strangeness sector. The experiment employs large-area Silicon Drift Detectors (SDDs) with a thickness of 450 μm, optimised for detecting soft X-rays. To extend the accessible energy range and enable precision measurements of...
Radiation and particle detection systems based on low-gain avalanche diodes (LGAD) are promising technologies for a broad range of applications spanning from timing detectors of minimum ionizing particles in High-Energy Physics (HEP) experiments to soft X-ray detectors in synchrotron, FEL and X-ray fluorescence analysis instruments. LGADs are expected to improve the performance of the...
Hybrid pixel detectors (HPDs) consist in a sensor absorbing the X-ray radiation, usually silicon, connected to the CMOS readout electronics, that processes the signal generated by the sensor signal on a pixel by pixel basis. They were spinned-off from high energy physics tracking applications to photon science at the beginning of the millennium, and they managed to be disruptive in both...
X-ray polarimetry is an observational technique with the potential to enrich our understanding of high-energy astrophysics via the measurement of the polarization of X-rays emitted by exotic cosmic phenomena such as black holes, neutron stars, Gamma-Ray Bursts and Solar flares, enabling to unveil new insights on fundamental physics and geometry of Galactic and extragalactic sources. We will...
Astrophysical X-ray polarimetry is a powerful technique for probing the physical conditions and emission mechanisms of cosmic X-ray sources. At energies below 50 keV, photoelectron track imaging is the leading method for measuring X-ray polarization. In this approach, the track of a photoelectron, produced when an X-ray photon is absorbed, is imaged to reconstruct its initial emission...
MÖNCH is a charge-integrating hybrid pixel detector readout ASIC with 25 μm pitch, currently in the advanced prototyping phase.The small pixel pitch offers excellent native spatial resolution performance which has been demonstrated with several applications such as, full-field fluorescence imaging, computed tomography, and ptychography. With the combination of low noise and charge sharing...
The HASPIDE project, funded by INFN, focuses on the development of hydrogenated amorphous silicon (a-Si:H) detectors for applications in X-ray dosimetry. These devices are fabricated on thin Kapton substrates, combining good mechanical flexibility with promising dosimetric performance. The control over the deposition process and the integration on flexible supports make this technology...
The study and the development of innovative imaging detectors represent a crucial element in the field of X-ray imaging, mainly to overcome some of the limits of the standard ones. In this work an overview of the main results obtained during the study and the development of imaging detectors based on optically active point defects produced by X radiation in lithium fluoride (LiF) crystals and...
The organometal halide perovskites (OMHP) semiconductors have been proven in the recent years to be promising material to detect ionization radiation, beside the well known success as photovoltaic devices.
In particular, OHMPs show large potential for X-rays detection due to their high stopping power, especially for energy above 30 keV where the Silicon absorption coefficient starts to...
