Description
The INFN Roma1 group has designed a new structure of all-in-one scintillator particle detectors, ArduSiPM, exploiting the latest innovations in silicon photomultiplier (SiPM) and System on Chip (SoC) technology.
We have minimized the external components to the analog ones, using intensively the internal peripherals of the microcontroller, making these devices compact and high-performance. Using firmware and off-the-shelf SoCs, instead of custom ASICs, reduces costs, accelerates development, and eases upgrades to new commercial SoCs.
Following this achievement, we are developing new generations of detectors that are smaller and more performant, first with MICRO and now with LITE-SLPD (Lightweight Silicon Pixel Detector), research projects by INFN.
The second generation was realized with Cosmo ArduSiPM, more powerful, compact, and suitable for space missions. Utilizing the Microchip SAMV71 320 MHz, ARM®Cortex®M7, including a Radiation-Tolerant version, this innovative detector incorporates two independent channels within a CubeSat form factor, weighing only 40 grams.
Additionally, a third generation, called NanoArduSiPM, characterized by even more compact dimensions (half the size), is currently undergoing testing.
Our compact electronic system cuts the need for external data acquisition systems and ASICs, allowing the CPU to perform edge computing functions.
The detector, capable of measuring the rate, the arrival time (with a resolution of 7 ns for the second and third generation, correlated to the main clock of the SoC), and the number of photons arriving on the SiPM, is ideal for radiation monitoring and highly sensitive photon detection.
Coupled with a fast plastic scintillator, this technology is used as a cosmic ray counter, trigger, or beam losses monitor in several experimental activities, meanwhile it can be used gamma detector with inorganic scintillating crystals, such as cesium iodide (CsI) or bismuth germanate (BGO)
Moreover, the firmware of Cosmo ArduSiPM can be configured for fast analysis and to produce the gamma spectrum.
