• Chaotic dynamics induced by space-charge waves in cyclotron resonance accelerators 

      Pakter, Renato; Caldas, Ibere Luiz; Couto, Flavia de Oliveira; Caetano, Tiberio Silva; Rizzato, Felipe Barbedo (1996) [Artigo de periódico]
      In this work, we analyze the effects produced by the inclusion of space-charge waves in a Hamiltonian model for a cyclotron resonant accelerator. We find that space charges impose limits on acceleration and that these ...
    • Self-consistent chaos and Arnold diffusion in a cyclotron-maser wave-particle system 

      Pakter, Renato; Couto, Flavia de Oliveira; Rizzato, Felipe Barbedo (1995) [Artigo de periódico]
      In this work, we search for the presence of chaos in a self-consistent model for the cyclotronresonance maser accelerator. Two characteristic regimes are identified. If the initial action variable of the accelerating ...
