  • Enhancement of ion beam charge states by electron vortices in a plasma optical device 
    Goncharov, A.; Maslov, V.; Brown, I. (Вопросы атомной науки и техники, 2005)
    We consider the possibility of enhancing the ionization charge states of beam ions by electron vortices excited in cylindrically symmetric plasma optical systems of finite length with crossed radial electric and longitudinal ...
  • Evolution of the modulated electron beam in the inhomogeneous plasma with linear density profile 
    Anisimov, I.O.; Kelnyk, O.I.; Soroka, S.V. (Вопросы атомной науки и техники, 2005)
    Evolution of the density profile of the modulated electron beam moving through the plasma with linear density profile is studied via computer simulation. Increase of the beam current and decrease of its velocity results ...
  • Excitation of eigen azimthal waves by annular charged particle beam 
    Girka, V.; Lapshin, V.; Puzyrkov, S. (Вопросы атомной науки и техники, 2005)
    Investigations of an interaction between charged-particle beams and hybrid waveguide structures are important for radio engineering and plasma electronics. It is the distinctive feature of the interaction between charged ...
  • Excitation of Langmuir oscillations in a semi-infinite dense plasma by laser pulse 
    Balakirev, V.A.; Karas’, I.V.; Karas’, V.I.; Fainberg, Ya.B.; Tolstoluzhsky, A.P. (Вопросы атомной науки и техники, 2005)
    Nonlinear mechanism of Langmuir wave excitation in dense plasma by intensive laser pulse has been investigated. Laser pulse has frequency ω=ω p /2 (where ω p is electron plasma frequency).
  • Experimental studies of some features of beam-plasma discharge initial stage 
    Butenko, V.I.; Ivanov, B.I.; Prishchepov, V.P. (Вопросы атомной науки и техники, 2005)
    In case of gas pressure increasing, the plasma density rapidly increases at p=(1-2)*10⁻⁴ Torr, due to the beam-plasma discharge start (BPD). For fixed pressure above 2*10⁻⁴ Torr, the BPD start depends from the interaction ...

    Azarenkov, N.A.; Bizyukov, A.A.; Lapshin, V.I.; Maslov, V.I.; Onishchenko, I.N.; Tarasov, I.K.; Tarasov, M.I.; Volkov, E.D. (Вопросы атомной науки и техники, 2005)
    In recent years a big attention is given to coherent structures at an explanation of phenomena of the fast convective carry from the scratch-off-layer in devices such as “tokamak” and “stellarator”. Coherent structures can ...
  • Fractal properties of dispersion characteristics of sinusoidally rippled plasma waveguide 
    Lapshyn, V.I.; Stoyanov, A.F.; Tkachenko, V.I.; Tkachenko, I.V. (Вопросы атомной науки и техники, 2005)
    Features of the solution of Maxwell’s equations in sinusoidally rippled waveguide with the metal walls, filled with cold plasma, are considered. The dispersion equation which gives connection between longitudinal wave ...
