“…The MAPD-3NK has high pixel density (≈10000 pix./mm 2 ), high PDE (≈40%) and large sensitive size (3.7 mm*3.7 mm). All these advantages make the MAPD-3NK devices the best candidate for most experiments and industry [5,18,19]. In this work, we demonstrate gamma ray and beta particle detection performance of new designed detector modules based on MAPD-3NK type MAPDs and NaI, LFS, p-terphenyl type scintillators.…”

In this paper presented the results of the ionizing radiation detector modules, which developed on the basis of a new generation of micropixel avalanche photodiode (MAPD) of MAPD-3NK type. The samples were produced in cooperation with the Zecotek Photonics and characterized by the following parameters: sensitive area—3.7 mm × 3.7 mm, density of pixels—10000 pixels/mm2, photon detection efficiency—35–40% (at wavelength of 450–550 nm) and operation voltage—91 V. The beta particle and gamma ray detection performance of MAPD with different single scintillation crystal such as NaI, LFS and p-terphenyl was investigated. The gamma ray detector modules demonstrated a perfect linear behavior of detected signal amplitudes as a function of the gamma ray energy (from 26.3 keV up to 1.33 MeV). Energy resolution for 662 keV gamma rays was 11.2% and the minimum detectable energy was 26.3 keV.

“…Данные детекторы вполне удовлетворяли требованиям, предъявляемым при поиске массы нейтрино в области низких энергий и обладающий большим быстродействием. В качестве возможных кандидатов на роль нового детектора рассматривались микроканальные пластины и экспериментальные образцы микропиксельных лавинных фотодиодов (МЛФД) без защитного покрытия с очень тонким входным окном [15]. Но микроканальные пластины не могут обеспечить отклик на воздействие электроном пропорциональный энергии электрона, т. е. нет возможности проводить спектрометрические измерения.…”

“…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.
