The Alpha Magnetic Spectrometer (AMS) was installed on the
International Space Station in 2011. This particle physics experiment
is designed to measure the composition of cosmic rays in low Earth
orbit, with the primary goal of distinguishing between antimatter and
matter. AMS is equipped with a permanent magnet and multiple detectors,
allowing it to analyze incoming cosmic rays with...
Scintillators such as EJ-200 plastic and LYSO inorganic crystals are widely used in current and future astroparticle physics experiments. However, significant discrepancies exist among reported measurements of light yield quenching for these materials that impacts the accuracy of expected detector responses. This study presents new experimental data obtained using muons, protons, carbon ions,...
High granularity 3D calorimeters offer the potential to precisely reconstruct the 3D topology of electromagnetic and hadronic showers originating from isotropic sources. This distinctive capability creates the opportunity for applying reconstruction and analysis methods that could yield additional information compared to those based on the traditional layer-by-layer energy deposit analysis...

Zirรจ is one of the payload of NUSES and aims to measure electrons, protons, and light nuclei in an kinetic energy range spanning from a few MeVs to several hundred MeVs, as well as photons in the energy range from 0.1 MeV to 10 MeV. Zirรจ consists of a Fiber...
Timepix3 [1] is a hybrid pixel detector with $55\,\mu\mathrm{m}$ pixel pitch in a matrix $256 \times 256$ pixels. It can measure in data-driven mode when it detects both the deposited energy and time of arrival (ToA) in the pixels. The ToA is written with $1.56\,\mathrm{ns}$ precision. The fine ToA resolution permits 3D reconstruction of tracks within the sensor [2]. This makes Compton camera...
Plastic scintillator detectors can provide charge measurement and participate in the anti-coincidence trigger system for gamma detection in space-born cosmic ray experiments, such as HERD (High Energy Cosmic Radiation Detection). In order to achieve its objective, the plastic scintillator bars will be equipped with two different kinds of silicon photomultipliers (SiPMs) for HighZ and LowZ...
The use of scintillating fiber detectors, read out with silicon photomultiplier (SiPM) arrays, has emerged as a promising technology for particle tracking in high-energy physics, cosmic-ray and gamma-ray astrophysics. The FIber Tracker (FIT), proposed for the upcoming High Energy cosmic-Radiation Detection (HERD) facility, provides a spatial resolution at the scale of tens of micrometers with...
A next-generation gamma-ray observatory operating in the medium-energy gamma-ray band (~100 keV to 100 MeV) will provide crucial capabilities needed to identify and classify multi-messenger sources and to probe the explosive and energetic processes in the universe including relativistic jets and gamma-ray bursts. Advancements in tracker detector technologies and instrument design are critical...

NUSES is a forthcoming space mission intended to test innovative observational and...
The China Seismo-Electromagnetic Satellite (CSES) mission is a collaborative effort between China and Italy aimed at building a constellation of multi-payload space observatories dedicated to studying Earthโs geophysical properties from space using non-imaging remote sensing methods. The project seeks to develop a network of small satellites that continuously gather data from the entire...
Gamma-Ray Bursts (GRBs) are among the most powerful and violent events in the Universe. Despite over half a century of observations of these transient sources, many open questions remain about their nature and the physical emission mechanisms at play. Polarization measurements of the GRB prompt ฮณ-ray emission have long been theorized to be able to answer most of these questions. With the aim...
The Large Area Detector (LAD) is an instrument concept for high-throughput spectral timing studies of compact astrophysical sources in the X-ray energy band (2-30 keV), originally proposed for the LOFT, eXTP and STROBE-X space missions. The LAD is based on an array of collimated large-area linear Silicon Drift Detectors (SDDs), that can be combined to accumulate a large effective area. The...
The counting process of individual physical events in the presence of an extended dead time (EDT) in the electronics results in the saturation and quenching of the counting rate, due to pile-up. This effect can be accounted for, on average, by inverting the saturation curve, provided the electronics double pulse resolution associated with the counting process is known. In the present work, we...
The Mini-EUSO mission operates from inside the International Space Station (ISS) to detect UV photons produced by ultra-high-energy cosmic rays (UHECRs), ELVES, meteors or other transient atmospheric or ground phenomena, using multi-anode photomultiplier tubes (MAPMTs) in single photoelectron counting mode. Because of the $\sim 6$ ns extended dead time (EDT) associated with the use of the...
