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.","PeriodicalId":36047,"journal":{"name":"Eurasian Journal of Physics and Functional Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135814772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The levels of the decrease in the sensitivity of analytical signals of internal standards and uranium spikes under the influence of the matrix effect were determined. The ratio of the measured concentration of internal standards in the background solution of 5% nitric acid and in the matrix of the urine simulator was found compared to uranium. Based on this, empirical coefficients were calculated that characterize the difference in the matrix influence on analytical signals of the internal standard and uranium signals. Adjustment applied was verified according to the internal standard using calculated empirical coefficients and measured values of analytical signals of the internal standard in samples and in the background solution.

In experiments with relativistic heavy ion reactions, a new phase of matter: quark-gluon plasma is being studied. It make possible to shed the light on the first seconds of the Universe existence, as well as to quantitatively describe the processes of neutron star merger. Ultra-high density nuclear matter states could be investigated in the collisions of heavy nuclei at energy range 4 - 11 GeV by studying of the particles yields which contained charm quarks in the Multi Purpose Detector experiment at the NICA collider. In this work, the concept of tracking detector was proposed together with the corresponding modeling of such detector whose inner layers consist of new generation large area thin (40 μm ) monolithic active pixel sensors, and whose outer layers are built of pixel sensors (50 μm ) currently used in high-energy physics experiments. The identification capability of a vertex detector that uses 40 μm and 50 μm thick pixel sensors was obtained. These data give the possibility to reconstruct the decays of D+ mesons produced in gold-gold collisions in the NICA complex.","PeriodicalId":36047,"journal":{"name":"Eurasian Journal of Physics and Functional Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135814940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
