F.; Ponomaryov, A. G.; Chumakov, V. I.The results of investigations on degradation effects in the radioelectronics circuit ryunder the influence of the high-intensity pulse radiation are given. Analysis of the mechanism of degradation because of hortening the radio pulse radiation wave length has been carried out. When the wavelength of the object, exposed to the radiation of a centimeter range, exceeds the characteristic size of structural elements, the degradation mechanism is conditioned by the quasi-static effects on the object structureinhomogeneities. The degradation effects manifest themselves in a c-cordance with the concept of a "weak link" and localization damage model. In the case of wavelength shortening, when the characteristic size of the objectstructure elementbecomes commensurable with the wavelength, the resonance effectaction is more and more increasing. The degradation redistribution occurs according to the field intensity distribution in the resonantregions. The problem of electromagnetic resistance lowering, under conditions of the tendency towards the radio electronics circuitry microminiaturization, is discussed.Публікація Operator method analysis of pulse-forming lines and screening(2018) Chumakov, V. I.; Kharchenko, O. I.In this paper the results of the operator method application to the analysis of processes in the pulseforming lines and the process of the electromagnetic field screening are presented. The model is considered as a system of Laplace transformed telegrapher’s equations and examples of its solution by the Fourier method and the method of traveling waves (d'Alembert method) are given. Wide perspectives the operator method has for solving problems of analysis of transient in linear devices and systems. The advantages of the operator method are shown, which makes it possible to simplify the analysis. It is shown also that the initial conditions of the problem are taken into account automatically. Examples of the solution of the charging problem of the orming line from the DC voltage source are considered and a comparative analysis of the results obtained by both methods is carried out. It is shown that the solution by the Fourier method allows obtaining an expression for the voltage in the line in the form of a spectral function and may be used at thefrequency domain analysis.Публікація Project of designing in khture high-energy plasma accelerator(2001) Volkolupov, Yu.Ya.; Krasnogolovets, M.

It’s well known that the radiation power, density and temperature of plasma in such sources depend on the power put in(inserted in, into) a discharge and therefore on a discharge current [1-5]. Space distribution of the temperature research in the field of discharge allow to optimize parameters of power-plant and construction of radiator for maximum (the highest possible) radiation efficiency obtaining.Публікація Pulse UV Sterilization of Viral Infection(2021) Chumakov, V.
