• Stochastic diffusion of energetic ions due to incoherent lower hybrid waves 

      Tozawa, Lucio Minoru; Ziebell, Luiz Fernando (2003) [Artículo de periódico]
      In the present paper we discuss stochastic diffusion of energetic ions by a set of lower hybrid waves with frequencies close to each other and random phases which change along the time evolution of the system. We obtain ...
    • Stochastic diffusion of energetic ions due to lower hybrid waves 

      Tozawa, Lucio Minoru; Ziebell, Luiz Fernando (1998) [Artículo de periódico]
      This paper discusses the interaction between energetic ions and lower hybrid waves in tokamak plasmas, presenting a numerical analysis which employs a quasilinear formalism appropriated for the situation in which ion ...
    • Stochastic diffusion of ions due to a finite set of lower hybrid waves 

      Tozawa, Lucio Minoru; Ziebell, Luiz Fernando (2002) [Artículo de periódico]
      In this paper we generalize the discussion on stochastic diffusion of energetic ions by lower hybrid waves by considering a case where a set of waves with similar frequencies is present in the system. In the particular ...
    • The threshold condition for stochastic diffusion of energetic ions due to lower hybrid waves 

      Ziebell, Luiz Fernando; Tozawa, Lucio Minoru (1998) [Artículo de periódico]
      In the present paper we consider the interaction between energetic ions and lower hybrid waves in tokamak plasmas and study the parametric dependence of the threshold condition for stochastic ion di usion. It is shown that ...
