Abstract Ion beams reflected from the bow shock are shown to excite ioncyclotron instability in the solar wind. For the parameters relevant to the solarwind upstream of the terrestrial bow shock the growth ▪ is found to be a significant fraction of the ion cyclotron frequency μ i for K ▪M ≳ 2. Here K is the wave vector and ▪M is the proton gyro radius. The corresponding wave frequency ω r is found to be from ∼ 0.5 to several times the ion gyrofrequency μ i. Since the group velocities of these waves are small they can efficiently interact with the plasma in and near the generating region.
