  • Characterization of plasma and emergent ion beam in a compact helicon source with permanent magnets 
    Virko, Yu.V.; Virko, V.F.; Shamrai, K.P.; Yakimenko, A.I. (Вопросы атомной науки и техники, 2007)
    A compact helicon source with multi-component changeable magnetic system was studied to gain enhanced parameters of plasma and emergent ion beam. Alteration of the magnetic field configuration was found to be the main ...
  • Helicon discharge excited by a planar antenna in bounded volume 
    Virko, V.F.; Slobodyan, V.M.; Shamrai, K.P.; Virko, Yu.V. (Вопросы атомной науки и техники, 2014)
    By direct spatial measurements of wave RF magnetic fields it is confirmed that the density jumps in the helicon discharge with a flat (planar) antenna result from changes in axial modes of standing helicon waves in a limited ...
  • Ion-acoustic wave activity in m = 0 helicon plasmas 
    Shamrai, K.P.; Virko, V.F.; Slobodyan, V.M.; Virko, Yu.V.; Kirichenko, G.S. (Вопросы атомной науки и техники, 2006)
    The results of experimental and theoretical study of low-frequency (LF) wave activity in a helicon plasma and in an inductively coupled magnetized plasma are presented. This activity is shown to relate to ion-acoustic ...
  • Modified helicon discharge excited by a linear inductive antenna 
    Borisenko, A.G.; Beloshenko, M.A.; Virko, V.F.; Virko, Yu.V.; Slobodyan, V.M. (Вопросы атомной науки и техники, 2014)
    A new modification of the helicon discharge capable of producing linearly uniform plasma is investigated. The discharge is excited in magnetic field by an inductive antenna consisting of two parallel linear conductors with ...
  • Nonlinear phenomena in helicon plasmas 
    Shamrai, K.P.; Slobodyan, V.M.; Virko, V.F.; Virko, Yu.V.; Gurin, A.A.; Kirichenko, G.S. (Вопросы атомной науки и техники, 2006)
    Nonlinear phenomena stimulated by enhanced longitudinal electric field arising near the metal surfaces in helicon plasmas are analyzed theoretically. Ponderomotive effect giving rise to nonlinear instability of the edge ...
  • Wave Phenomena in Helicon Plasma 
    Virko, V.F.; Kirichenko, G.S.; Shamrai, K.P. (Вопросы атомной науки и техники, 2003)
    Employing of the electrodeless, low-pressure inductive discharges (ICPs) is preferable in many applications. A helicon discharge, which is known as the most efficient magnetized ICP [1], operates with excitation of ...
  • Сontrolling parameters determining technological properties of a helicon discharge system 
    Semenyuk, V.F.; Virko, V.F.; Korotash, I.V.; Osipov, L.S.; Polotsky, D.Yu.; Rudenko, E.M.; Slobodyan, V.M.; Shamrai, K.P. (Вопросы атомной науки и техники, 2013)
    In experiments on two helicon sources driven by a planar antenna, it is shown that the plasma density in the drift chamber and the energies and density of the ion flux onto the substrate holder can be effectively controlled ...
