TLDR
In this paper, the properties of radio waves generated by electron beams in space were investigated using data from the wideband wave receiver on the Spacelab 2, which was found to confirm the results of the STS 3/OSS-1 mission.Abstract:
The properties of radio waves generated by electron beams in space were investigated using data from the wideband wave receiver on the Spacelab 2. The VLF observations were found to confirm the results of the STS 3/OSS-1 mission. It was found that a 1-keV electron beam injected from the orbiter produced copious broadband electromagnetic emissions. When the electron beam was square-wave modulated, narrow-band emissions at the pulsing frequency and harmonics of that frequency were produced along with the broadband emissions. The observations indicated that dc 50-mA electron beams and pulsed 50-percent duty-cycle 100-mA beams produce broadband radiation which is comparable in intensity and spectral shape at all points for which the wave field was sampled.read more

Torsten Neubert,Peter M. Banks +1 more
TL;DR: In this article, the authors examined selected results from experiments, performed in 1980s, involving the ejection of beams of electrons from spacecraft, and special attention was given to the basic processes associated with the spacecraft charging, passive current collection, beam-atmosphere interactions, beamplasma interactions, and neutral gas emission.

International reference ionosphere: Recent developments
TL;DR: In this article, the International Reference Ionosphere (IRI) model is compared with the AEROS satellite data and it is shown that the IRI model is inaccurate in its description of the latitudinal behavior of the electron density in the ionosphere close to the magnetic equator.

Whistler‐mode radiation from the Spacelab 2 electron beam
TL;DR: In this paper, a fly-around of the Shuttle at distances of up to 300 meters while an electron beam was being ejected from the Shuttle was discussed, and it was shown that the shape of the funnel can be accounted for by whistler-mode waves propagating near the resonance cone.
