Modern unmanned technologies make it possible to implement them in almost all industries, including radiation monitoring. Already in 2011, at the Fukushima nuclear power plant accident, the first drones were demonstrated to measure the radiation background of the territories. Improvement of such devices is one of the topical directions. Our research team has proposed the concept of a gamma radiation detector module for unmanned aerial vehicles. The concept is represented by a matrix of modernized silicon photomultipliers based on silicon structures. The new structures have a design of deep pixel photodiodes of the MLPD type. Today's experimental samples have superiority in such parameters as high efficiency of registration of ionizing radiation. Also, such parameters as low sensitivity to vibrations and low power consumption of photodiodes make it possible to integrate them into unmanned and small-sized radiation monitoring systems.

“…An increase in the pixel area (𝐶 𝑝 is proportional to 𝑆 𝑝 ) allowed reaching the photodiode gain ∼ 3 • 10 4 , and PDE ∼ 15% [19]. However, MAPD further increase of the PDE to levels beyond 20%, may be necessary for some medical applications, high energy physics experiments and public security [20][21][22][23][24][25][26][27][28][29][30][31][32]. The gain and PDE of MAPD photodiodes were further improved by increasing the pixel diameter to 5 μm, and the pitch to 7 μm.…”

The paper is concerned with the parameter study of a new generation of micro-pixel avalanche photodiodes (MAPD) with deeply buried pixel structure, also named silicon photomultipliers (SiPM) or multi-pixel photon counter (MPPC). The new MAPD of type MAPD-3NM was manufactured in the frame of collaboration with Zecotek Company. Measurements were carried out and discussed in terms of the important parameters such as the current-voltage and capacitance-voltage characteristic, gain, the temperature coefficient of breakdown voltage, breakdown voltage, and gamma-ray detection performance using an LFS scintillator. The obtained results showed that the newly developed MAPD-3NM photodiode outperformed the previous generation in most parameters and can be successfully applied in space application, medicine, high-energy physics, and security. New proposals are also discussed, for further improvement of the parameters of the MAPD photodiodes that will be produced in the coming years.

“…Therefore, scintillation detectors based on new photosensors are quite promising candidates that meet the requirements much better, and focusing on their further development is in high demand 9 – 22 . Many research teams focus on the development of scintillation detectors based on micro pixel avalanche photodiodes (MAPD) or silicon avalanche photomultipliers (SiPM) 15 – 26 . The parameters of latest SiPM generations allows them to become applicable as effective sensor element replacements of PMT in scintillation detectors.…”

This paper presents the gamma-ray detection performance of the newly developed MAPD-3NM-II type SiPM sensor array (4 $$\times$$ × 4) with $$\hbox {LaBr}_3$$ LaBr 3 (Ce) scintillator. The gamma-ray spectra of various sources have been measured in the energy range from 26 keV up to 1332 keV. The newly developed array based on MAPD-3NM-II sensors proved $$\sim$$ ∼ 22% enhancement in energy resolution in comparison to the former MAPD-3NM-I based array. The energy resolution of 662 keV gamma-rays measured by MAPD-3NM-II was 3.3% while clearly surpassing 4.25% resolution of MAPD-3NM-I predecessor. The enhancement is related to the high PDE of the new MAPD-3NM-II. Obtained results show that the new MAPD-3NM-II demonstrated good energy resolution and linearity in the studied energy region. The energy resolution of the new detector developed based on MAPD-3NM-II was better than all previous products of MAPD.
