  • About generation of subharmonics and stochatic regimes arising in periodic plasma-filled waveguides excited by charged beam 
    Babaskin, A.A.; Kirichok, A.V.; Kuklin, V.М.; Mouharov, S.Т.; Zaginajlov, G.I. (Вопросы атомной науки и техники, 2000)
    Various mechanisms for generation of subharmonics in periodic plasma-filled waveguides excited by charged beam are considered. It is shown that beam particles seized by the excited electromagnetic wave can demonstrate under ...
  • Dynamics of ions during development of parametric instability of langmuir waves 
    Belkin, E.V.; Kirichok, A.V.; Kuklin, V.M.; Pryjmak, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    Nonlinear regimes of one-dimensional parametric instabilities of long-wave plasma waves are considered for the cases when the average field energy density is less (Zakharov’s model) or greater (Silin’s model) than the ...
  • Ion kinetics and ion sound generation under the development of modulation instability of an intense Langmuir wave in a plasma 
    Kirichok, A.V.; Kuklin, V.M.; Pryimak, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2015)
    The development of one-dimensional parametric instabilities of intense long-wave plasma waves is considered in terms of the so-called hybrid models, when electrons are treated as a fluid and ions are regarded as particles. ...
  • Modelling of superradiation processes driven by an ultra-short bunch of charged particles moving through a plasma 
    Kirichok, A.V.; Kuklin, V.M.; Mischin, A.V.; Pryimak, A.V. (Вопросы атомной науки и техники, 2015)
    The specific features of the superradiation processes excited by an ultra-short 1D monoenergetic bunch of charged particles, which moves through a plasma, are examined. When the size of the bunch is less then the wavelength ...
  • On the emission spectrum of oscillator trapped in a potential well 
    Kirichok, A.V.; Kuklin, V.M.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    We study the spectrum of electromagnetic waves emitted by oscillator, trapped in an external potential well. It is assumed that the natural frequency of the oscillator is much greater than the frequency of oscillations in ...
  • On the formation of pulses of coherent radiation in weakly inverted media 
    Kirichok, A.V.; Kuklin, V.M.; Mischin, A.V.; Pryjmak, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2013)
    A change in the character of maser generation in a two-level system is found when the initial population inversion exceeds some threshold value equal to the square root of the total number of atoms. Above this threshold, ...
  • On the nature of sources of pulsating radiation in weakly inverted media 
    Kirichok, A.V.; Kuklin, V.M.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2015)
    The conditions for the occurrence of a periodic sequence of pulses of coherent radiation in a weakly inverted two-level medium are investigated. It is studied the dependence of the pulse period and amplitude on the inversion ...
  • Structural-phase transitions and state function in unstable convective medium 
    Gushchin, I.V.; Kirichok, A.V.; Kuklin, V.M. (Вопросы атомной науки и техники, 2015)
    Convection in a thin layer of liquid (gas) with temperature independent viscosity between poorly heat conducting boundaries is studied within framework of the Proctor-Sivashinsky model. We have shown by numerical simulation ...
  • Оn pulsating radiation in weakly inverted media 
    Kirichok, A.V.; Kuklin, V.M.; Mischin, A.V.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2018)
    A change in the character of maser generation in a two-level system is found when the initial population inversion exceeds some threshold value equal to the square root of the total number of atoms. Above this threshold, ...
