This method describes the simultaneous distribution of lithium ions on surfaces of cylindrical silicon crystals, which speeds up the process of obtaining the required detector structure. Here in this work, we aimed to identify the most optimal regimes of the electric field applied in the process of bilateral ion drift, as well as to investigate the effect of the thermal factors to create a drift of lithium ions. We can estimate these optimal regimes of voltage and temperature by making theoretical assumptions based on the numerical method for solving the Poisson continuity equation, the calculations of Pell and Louber. At the same time, simplifications were made to neglect the internal interaction of particles. The paper shows the results of modeling the process of bilateral drift under the influence of a stepwise increase in temperature and reverse voltage. This bilateral drift procedure facilitates the fabrication of silicon-lithium nuclear radiation detectors with large diameters and sensitive areas.","PeriodicalId":321102,"journal":{"name":"Physical Sciences and Technology","volume":"81A 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121165800","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 expected effect in this case is to increase the contrast of images of noctilucent clouds fields and other extended objects, as well as the registration of new types of meteor phenomena. The implementation of the task involves the use of receivers that are available at the CAR of the NKU, including digital cameras, an optical image amplifier and infrared light filters. As a result of testing the devices, the CANON 2000 model with CANONZOOMLENSEF-S 10-22 lens was recognized as the most promising digital camera, which has the largest field of view with good image quality. This camera has been successfully used for optical registration of noctilucent clouds and meteors. Its application for observations in the infrared range was achieved by using a light filter 093 = RG830. Experiments conducted to obtain daytime images of tropospheric clouds and images of noctilucent clouds have yielded positive results. In addition, experiments were carried out to obtain infrared images of cloud fields by using the NPM-8 KM complex (electronic brightness amplifier) + CANON 600D (digital camera), which can also be considered successful within the framework of the task being implemented. The prospects of using this equipment for solving scientific problems are","PeriodicalId":321102,"journal":{"name":"Physical Sciences and Technology","volume":"24 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113979229","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}

In the work, a computer model of a universal cryo surface with automatic maintenance of a given temperature in the range from 80 K to 300 K was created, which is intended for efficient production, taking into account all possible wishes of the system user and solving a wide range of problems. In the course of the study, working drawings of the cryo surface were obtained, a computer model of a universal cryo plate was developed, and thermophysical processes in it were studied. Based on the created mesh of the model and the results of the consumption of the working cryo-liquid, the optimal temperature values of the cryo surface were determined. With the help of this development, the problems of innovative materials processing technologies will be solved when creating a heat exchanger and substrate, creating an efficient pump for cryo-liquid, as well as creating a temperature maintenance system of various accuracy. The result will be a system with compactness, versatility, and autonomy.","PeriodicalId":321102,"journal":{"name":"Physical Sciences and Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129960320","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}
