Scientific paper

Accurate measurements of some parameters of an artificial xenon ion beam propagating in an ionospheric plasma have been obtained by using a radiofrequency probe. The electron density profile inside the beam is studied as a function of the distance from the xenon source as it travels across the magnetic field lines. For distances small compared to the ion gyroradius, the electron density follows an analytical law which expresses conservation of flux of the number of ions through the beam cross section, proving that the beam is neutralized at very short distances from the source. At short distances from the source, the HF turbulence is concentrated at the front edge of the beam; with increasing distance, the density gradients are smoother and the turbulence weaker. Another type of HF turbulence generated by a destabilization of the harmonics of the electron gyrofrequency is detected in regions of low-density plasma preceding the beam edge.
