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 ...

The detection efficiency study of NaI(Tl) scintillation detector with the different numbers of SiPMs

Nuclear Engineering and Technology, 2022
SiPMs are generally coupled into whole columns in gamma energy spectrum measurement, but the relationship between the distribution of whole SiPM columns and the energy resolution of the measured energy spectra is rarely reported.

Understanding and simulating SiPMs

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2019
Abstract The silicon-photomultiplier (SiPM) is becoming the device of choice for different applications, for example in fast timing like in time of flight positron emission tomography (TOF-PET) and in high energy physics (HEP). It is also becoming a choice in many single-photon or few-photon based applications, like for spectroscopy, quantum ...

A CMOS ASIC design for SiPM arrays [PDF]

2011 IEEE Nuclear Science Symposium Conference Record, 2011
Our lab has previously reported on novel board-level readout electronics for an 8×8 silicon photomultiplier (SiPM) array featuring row/column summation technique to reduce the hardware requirements for signal processing. We are taking the next step by implementing a monolithic CMOS chip which is based on the row-column architecture.

SiPM批量老练和性能测量系统研制

He jishu
硅光电倍增管（Silicon Photomultiplier，SiPM）作为近年来发展的一种新型光电探测器件，具有低成本、小型化、工作电压低等优势，已广泛应用于粒子探测、医学成像、高能物理等领域，特别是在大面积粒子成像领域，有着广阔的应用前景。但大面积成像需要大量的SiPM，实现大量SiPM的批量筛选、老练和性能测量至关重要。本文研究设计了一套SiPM批量性能测量系统，可实现对512个（数量可进一步拓展）SiPM的同时老练和性能测量。通过编制在线控制程序，对大量SiPM轮询测量，实现老练和性能 ...
