Observation of Chaotic Behavior Caused by Ion-Ion Instability

抄録

By setting a mesh grid as a boundary condition in the ion-beam-plasma system, we attempted to observe chaotic behavior caused by the ion-ion instability. In the presence of the mesh grid the ion-ion instability showed chaotic behavior. The estimated correlation dimension was a noninteger value larger than 3. Furthermore, the spatial energy distribution of ions was measured two dimensionally with an energy analyzer, suggesting that the present system is one dimensional.
