A finite-amplitude cyclotron wave which has arisen as a result of the cyclotron instability in a plasma in an open confinement system is unstable against the excitation of cyclotron waves of a different azimuthal mode and low-frequency flute waves (drift waves with k/sub parallel/approx. =0). The nonlinear coupling of the low-frequency waves with the cyclotron waves is based on the displacement of electrons along the magnetic field B. The longitudinal motion turns out to be important in the flute waves because the plasma is bounded in the direction along B. Since the damping rate for the linear cyclotron wave is larger than that for the flute waves, the instability is dissipative. (AIP)
