    Compact and sustainable electronic module for silicon photodetectors
    (L.N. Gumilyov Eurasian National University, 2023) Sadigov, A.; Nuruyev, S.; Akbarov, R.; Berikov, D.B.; Madadzada, A.; Mammadli, A.; Lyubchyk, S.
    This article presents the development of a cost-effective and efficient electronic module for silicon photodetectors (SiPM). The electronic module combines essential functionalities, such as a high voltage power supply, a preamplifier, and a signal comparator, into a compact circuit. A high voltage power supply with a range of 30 to 140 V provides a stable bias voltage with 0.01 V accuracy, while a preamplifier with 40 gain and 250 MHz bandwidth enables signal amplification necessary to extract weak signals. The comparator converts an analogue signal (higher than 8 mV) into TTL (transistor-transistor logic), which makes it easy to process and analyze with digital devices such as microcontrollers or make it possible to send signals over long distances by a cable. The module has been tested using an LYSO scintillator and a silicon photomultiplier (SiPM) called a micropixel avalanche photodiode (MAPD). It provides a more effective and efficient solution for reading out signals from SiPMs in a variety of applications, delivering reliable and accurate results in real-time. © (2023).

    Investigation of parameters of new MAPD-3NM silicon photomultipliers
    (IOP Publishing Ltd, 2022) Ahmadov, F.; Ahmadov, G.; Akbarov, R.; Aktağ, Aliekber; Budak, Erhan; Doğancı, Emre; Gürer, Umutcan; Karaçalı, Hüseyin
    In the presented work, the parameters of a new MAPD-3NM-II photodiode with buried pixel structure manufactured in cooperation with Zecotek Company are investigated. The photon detection efficiency, gain, capacitance and gamma-ray detection performance of photodiodes are studied. The SPECTRIG MAPD is used to measure the parameters of the MAPD-3NM-II and scintillation detector based on it. The obtained results show that the newly developed MAPD3NM-II photodiode outperforms its counterparts in most parameters and it can be successfully applied in space application, medicine, high-energy physics and security.
