Abstract
A nonlinear theory is presented for the saturation of the current-driven ion-acoustic instability. The saturation mechanism is the modification of ion orbits by finite-amplitude waves, leading to ion trapping. The results are quantitatively compared with recent computer simulations of Biskamp and Chodura, and experiments of Hamberger and Jancarik.Keywords
