A theory is presented for the nonlinear evolution of the beam cyclotron instability, together with the results of a series of computer experiments confirming the main points of the theory. The authors conclude that at a turbulent level which is proportional to Omega sub CEomega sub pe squared, a transition is made to the nonmagnetic ion acoustic instability. For small T sub iT sub e, the system then evolves until the fluctuating fields become strong enough to stabilize by ion trapping. Author
