Cosmo-ArduSiPM: a New Dual-Channel Particle and Light Detector for CubeSat Missions and Earth Applications

Our INFN Roma1 group has developed a novel architecture of all-in-one scintillator particle detectors, ArduSiPM, utilizing the latest advances in silicon photomultiplier sensors (SiPM) and System on Chip (SoC) technology. By intensively using the internal peripherals of the microcontroller, we have reduced external components to analog parts only, making these devices compact and high-performance. Building on this success, we have now created an even more powerful and compact device, Cosmo ArduSiPM, suitable for space missions. This new detector employs the Microchip SAMV71 320 MHz, 32-Bit ARM® Cortex®-M7, and has two independent channels within a CubeSat form factor weighing only 40 grams. Configurable firmware can be customized to suit various applications and can be seamlessly integrated with different Cubesat On-Board Computers. CosmoArduSiPM can also be operated standalone using its USB interface, which expands its usability for ground-based applications. The analog front-end of Cosmo-ArduSiPM is essentially identical to ArduSiPM, allowing for continued development of the technology. The use of software and SoC capabilities in the ArduSiPM architecture, instead of custom ASICs, provides significant advantages in cost and development time, while upgrades to new commercial SoCs remain easy. We are excited to present our innovative detector technology and its applications at this conference.
