Nonlinear wave-particle interaction leading to chaotic ion motion in the magnetosphere

Research output: Chapter in Book/Report/Conference proceedingChapter


The interaction between a bouncing proton and a kinetic Alfvén wave in the magneto-sphere is studied using a simplified model and a Hamiltonian averaged over the g5rration period of the protons. Both transverse and parallel components of the wave electric fields are included in the formulation. Significant chaotic motion is observed for relatively small wave amplitudes, which may explain observed effects. The results also show that the chaotic level increases considerably when protons bounce resonantly with the wave.
