A simple model of e.m. emission created by the electron beam moving in the time varying selfconsisting electrostatic potential is presented. In the model the one dimensional electron beam is injected from the a charging up body to which the one dimensional plasma neutralisation current is coming. The calculation were related to the observation on the electron emitting payload Gruziya-60-Spurt.

Observations of plasma effects due to an energetic electron beam near a rocket payload are summarized and an attempt is made to outline the basic processes in the plasma such as beam plasma discharge (BPD). The experiment had some unique features such as a high apogee and low background plasma density. The measurements covered most parameters relevant for the study of plasma effects, as well as payload potential, optical and radio emissions, energetic charged particles and plasma densities. Among the noteworthy observations are radio emissions up to VHP frequencies and very high payload potentials which even exceeded the gun voltage. The observed features are interpreted as BPD at low altitudes and as discharges in the E × B field at other heights.

Laboratory results of beam plasma discharge (BPD) (dimensions several metres) in a homogeneous atmosphere and a jet of neutral gas are presented. The beam was obtained by an electron gun of the same type as used in rocket experiments.

This paper describes two rocket experiments “Aelita” with high power lithium plasma injection. The results of onboard magnetometer, massspectrometer, photometer, plasma, corpuscular and ground radar measurements are given. Dynamics and structure of plasma formation are discussed.
