An investigation of an artificial electron beam injection into the ionosphere, carried out September 11, 1975, on the Zarnitsa-2 experiment, is described. Two beams of electrons were injected: (1) with an energy of 9.3 keV and a beam current of 270 mA, (altitude range of 109-136 km) and (2) with an energy of 7 kev and a beam current of 450 mA (altitude range of 136-154 km). Special attention was paid to radio emissions in the near rocket region at frequencies 10 times higher than the plasma and cyclotron frequencies of the undisturbed ionosphere plasma. The observed luminosity in the near-rocket region suggests an increase of the number of ionospheric electrons with energies at least up to several eV, attributable to: (1) acceleration by the rocket's electric field, and (2) heating by beam-generated plasma oscillations. The latter was found to be of primary importance, and a collective heating mechanism, giving rise to an avalanche-type plasma-density increase in a sufficiently dense neutral atmosphere is discussed.
