We shall consider the strongly non-local interactions of two ion cyclotron waves at small scales on one whistler wave at large scales. There are an infinite number of these modes: one for each cyclotron harmonic. Here the oscillations near the cathode due to the proximity of the lower cyclotron resonance in phase space can be more clearly seen. In all of these models the ion cyclotron frequency is assumed, and verified to be, much larger than the ion-ion collision frequency. At this stage of the computation, they thus have, in particular, nothing to do with the cyclotron resonance condition. The bounce spectrum has been investigated for the case of cyclotron interaction. An important difference is the location of the appearance of the lower cyclotron resonance in relation to the operating point. The purpose of this paper is to study the original direction of the radiation excited by electron cyclotron maser instability or the beam-plasma instability. In a plasma with negatively charged dust, electrostatic dust cyclotron waves can be driven unstable by ions drifting along the magnetic field. For the finite strength magnetic field, the transverse beam perturbation cannot be ignored and leads to the slow cyclotron instability. For tightly focused beams, the power absorption near the plasma frequency is of the same order of magnitude as near the cyclotron resonant frequency. The power absorption for unit length near the cyclotron frequency and the plasma frequency are determined. We can easily find the 0 particle pitch angle for which the number of the cyclotron harmonics contributing to (2.11) is maximum. The corresponding wavelength is infinite and the frequency is the ion cyclotron frequency or one of its harmonics. They also could be generated by ion-cyclotron heating. |
