Experiments were carried out on high current electron accelerator “Kalmar” at beam current up to 45 kA and electron energy up to 300 keV. Laser shadow streak image was used to visualize the dynamics of shock waves in transparent materials. Three-dimensional numerical simulation of gasdynamic phenomena in the diode gap and elastoplastic phenomena that depend on them in the target material was performed using MARPLE3D multiphysics software package. The new technique was designed for end-to-end modeling including heating and evaporation of the target under the action of the electron beam and nonlinear wave processes leading to internal fractures and spalling phenomena in the target material. We use wide-range equation of state for the description of the liquid and solid phases of matter at low temperatures. Appropriate modeling of this complex problem is based on high resolution numerical methods as well as on high performance computing. The implemented computer models are verified by experimental data. The developed software can be used for numerical stress-strain analysis of various structural units loaded by strong pulsed forces and/or energy fluxes.","PeriodicalId":156877,"journal":{"name":"8th International Congress on Energy Fluxes and Radiation Effects","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128452675","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 projection of the magnetic field on the axes, which reflect the bonds of the carbon atom vacancy with the neighboring carbon atoms and the nitrogen atom, is calculated in this work. The paper highlights the algorithmic representation of the above calculations by software. The dependence of the optically detected magnetic resonance on the direction and magnitude of the magnetic induction vector is demonstrated. In total, there are 4 bonds between the vacancy and neighboring atoms located at an angle of 109.5° relative to each other. Having the magnitude of the ODMR signal, it is possible to reconstruct the vector of the external magnetic field, taking into account its projection angle on the bonds with the vacancy.","PeriodicalId":156877,"journal":{"name":"8th International Congress on Energy Fluxes and Radiation Effects","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126793061","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}
