Cosmo ArduSiPM: An All-in-One Scintillation-Based Particle Detector for Earth and Space Application.

Area of Science:

• Particle Physics Instrumentation
• Aerospace Technology
• Detector Development

Background:

• The first all-in-one scintillator particle detector, ArduSiPM, was developed in 2012 using silicon photomultiplier sensors (SiPMs) and system-on-chip (SoC) technology.
• Advancements in radiation-tolerant SoCs and the need for reduced system size and weight for space missions motivated the development of a new detector.

Purpose of the Study:

• To introduce the Cosmo ArduSiPM, a second-generation, improved-performance particle detector designed for space missions.
• To detail the architecture and capabilities of the new detector, highlighting its suitability for CubeSat modules and its advantages over custom ASIC systems.

Main Methods:

• The new detector, Cosmo ArduSiPM, is based on the Microchip SAMV71 300 MHz, 32-bit ARM Cortex-M7 SoC.
• It features an analog front-end similar to the original ArduSiPM but uses miniaturized components, fitting within a CubeSat module.
• The design incorporates two independent channels with a total weight of 40 grams.

Main Results:

• The Cosmo ArduSiPM architecture leverages commercial SoCs, offering significant cost and development time benefits compared to custom ASIC solutions.
• The compact, dual-channel board weighs only 40 grams and fits within a CubeSat form factor.
• Hardware characterization and system response to varying photon fluxes were detailed, with preliminary scintillator coupling tests showing potential for enhanced capabilities.

Conclusions:

• The Cosmo ArduSiPM represents a significant advancement in particle detector technology for space applications, offering a compact, lightweight, and cost-effective solution.
• Its architecture, based on readily available SoCs, ensures adaptability and sustained growth potential.
• The detector shows promise for future enhancements and broader applications in scientific research and space missions.
