Characterizing the Signals and Backgrounds in a Low Earth Orbiting Cherenkov Detector, and Background Mitigation Strategies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐

SiPMs for cryogenic temperature

Il Nuovo Cimento C, 2019
The DarkSide-20k collaboration is preparing to equip 20 m^2 of SiPMs working in liquid argon at 86 K for the direct search of WIMPs. The collaboration had to solve many technological aspects, such as the development of SiPM optimized for operation in liquid argon, the readout of large SiPM-based detectors, the reliable packaging of more than 200000 ...

Metal Ion Doping in Cs3Cu2I5 Crystals: Strategies to Regulate the Optoelectronic Property for Enhanced X‐Ray Scintillation and Imaging

Small Structures, Volume 7, Issue 2, February 2026.
This review mainly summarizes the synthesis, optical properties, and underlying mechanisms of metal ion doping (including Tl+, In+, Mn2+, alkali metals, and alkaline earth metals) in tailoring the optoelectronic properties of Cs3Cu2I5 crystals for scintillation applications. Besides, it highlights the emerging application prospects of Cs3Cu2I5 crystals,

Beyond mechanics: Maximum‐likelihood‐driven PET detector alignment calibration

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background Accurate quantification is a cornerstone of positron‐emission tomography (PET), yet mechanical inaccuracies during detector assembly continue to undermine this goal. Deviations from intended design geometries arise due to factors such as manufacturing tolerances, mechanical stress, and cumulative errors during module installation ...

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout
