Background:
Compact electronic modules are essential for modern detector systems utilizing Silicon Photomultiplier (SiPM) arrays due to their small size, low power consumption, and high precision. To address the growing demand for portable and efficient detection systems, the development of modules tailored for such applications has become a critical focus. This study introduces compact electronic modules designed for detectors based on MAPD (Microcell Avalanche Photodiode) arrays, aiming to improve reliability and versatility for industrial, medical, and scientific applications.
Methods:
The developed modules include two primary components:DC-DC Voltage Converter: Based on the MAX1932ETC chip.Converts a 5 V input to a stable output voltage adjustable between 30 and 90 V.Supports a maximum current of 2.5 mA, ensuring reliable operation for SiPM arrays.Signal Amplification Unit: Utilizes the LTC6268 chip.Processes input signals ranging from 10 to 75 mV.Offers a gain factor of 45, characterized by low noise and high precision.The modules were integrated with a scintillation detector comprising a MAPD-3NM-II photodiode array and an LFs scintillator. Performance testing was conducted using a Cs-137 gamma source.
Results:
The energy resolution of the detector system was evaluated using the 662 keV gamma line from the Cs-137 source. The modules achieved an energy resolution of 10 ± 0.5%, demonstrating high reliability and efficiency. This performance confirms the modules' capability to maintain stable operation and precise signal processing under real-world conditions.
Conclusions:
The developed compact electronic modules provide a cost-effective and efficient solution for detectors utilizing SiPM arrays. Their stable voltage conversion, low-noise signal amplification, and high energy resolution make them suitable for a wide range of applications in industrial, medical, and scientific fields. Future work may focus on optimizing the modules for broader voltage ranges and compatibility with different scintillator materials to expand their applicability.
