  • Azimuthal surface waves in toroidal magnetic traps 
    Girka, I.O.; Girka, O.I.; Girka, V.O.; Pavlenko, I.V. (Вопросы атомной науки и техники, 2008)
    Extraordinary polarized electromagnetic surface waves are known to propagate with zero axial wave number (kz=0) along the small azimuth j nearby the interface of a cold uniform plasma located in cylindrical metal chambers ...
  • Buildup of plasma oscillations during modeling the electromagnetic wave propagation

    Girka, O.I.; Girka, I.O.; Girka, V.O.; Pavlenko, I.V. (Вопросы атомной науки и техники, 2006)
    Coupled surface extraordinarily polarized waves and bulk ordinarily polarized waves are proved to propagate along azimuthal direction in the cylindrical metal waveguide that is partially filled by cold magneto-active ...
  • Effect of plasma rotation on the resonance magnetic perturbations at the edge of tokamak plasmas 
    Pankratov, I.M.; Pavlenko, I.V.; Pomazan, O.A.; Omelchenko, A.Ya. (Вопросы атомной науки и техники, 2012)
    In the frame of one-fluid MHD the pressure perturbation resonant excitation by external low frequency helical magnetic perturbations near the plasma edge is investigated. The plasma rotation plays a key role in this ...
  • Effect of the minority ions on the ICRF heating of fusion plasmas 
    Pavlenko, I.V.; Girka, I.O.; Leviga, B.I. (Вопросы атомной науки и техники, 2012)
    Additional plasma heating, for example ICRF (Ion Cyclotron Range of Frequencies) heating, allows heating only a group of the fuel particles which will initiate the thermonuclear fusion reaction. But the ICRF heating scenarios ...
  • Fast Alfvén wave propagation in milticomponent nonuniform plasmas 
    Kazakov, Ye.O.; Pavlenko, I.V.; Girka, I.O.; Weyssow, B. (Вопросы атомной науки и техники, 2008)
    The problem of the conversion, reflection and transmission of the fast Alfvén wave propagating in multicomponent nonuniform plasmas is studied. The dependences of the wave scattering characteristics on the plasma composition ...
