The distributions of beams of fast particles in the high-latitude ionosphere have been studied on the basis of measurements taken on the satellite Oreol-Z. The generation of a beam is associated with reconnection in the remote regions of the magnetospheric tail. The subsequent drift of the accelerated plasma in the transverse electric field gives rise to structures of precipitating particles with an energy dispersion.
