“…Full understanding of the coexistence and competition between various instabilities requires dedicated simulations which would take into account many unique characteristics of the APEX experimental setup, but such APEX-related simulation models have not been developed. Baranets et al (2007Baranets et al ( , 2012Baranets et al ( , 2017 presented non-linear theoretical analysis of beam-plasma interaction for systems of electron beam nested in or opposite to the ion beam that were related to the APEX injection configurations. Fast electrons from the MAGION-3 observations were explained as a result waveparticle interaction: whistler waves excitation by the electroncyclotron resonance and subsequent scattering.…”

“…Recent papers (Baranets et al, 2012(Baranets et al, , 2017, analysing the stationary electron beam injection (F40K modulation mode, 2µs pulses) with simultaneous xenon neutral gas/plasma release (Figure 10B), reported a number of beam-plasma interaction effects both in the vicinity of the injecting satellite and in the far zone (subsatellite observations at distance about hundred kilometers, see also section 3.4.2). Based on thermal plasma ion fluxes, photometric, and wave data they found their correlation with beats of the density and velocity waves in the beam core in the high-frequency parallel and perpendicular wave fields.…”

“…Recently, very detail analyses of the beam-plasma instability development, excitation of VLF/LF and HF waves, coupling of waves, particle heating and acceleration related to different APEX experiment configurations (injections through/opposite the xenon plasma cloud, quasi-perpendicular electron beam injections, injections of differently modulated electron beam -S250, F40K modes) have been performed in a series of papers by Baranets et al (2007Baranets et al ( , 2012Baranets et al ( , 2017 where the authors compared theoretically derived quantities with data obtained onboard IK-25 (VLF/HF emissions, electric and magnetic field fluctuations, plasma parameters) and remotely by MAGION-3 (HF emissions, accelerated electron fluxes, thermal plasma parameters). Presented results reflect the development of a beam or beam-anisotropic instabilities in the ionospheric plasma, some of them being a consequence of more complex combination (nonlinear) mechanisms of interaction, developing during injection of a beam into a beam.…”

We present the results of the active space experiment with charged particle beam's injection (electrons and xenon ions) carried out onboard Intercosmos-25 station and daughter Magion-3 subsatellite. The ones are obtained under conditions when the particle beams were injected in opposite directions relative to the magnetic field B0 in such a way that the electron injection was directed towards the Earth. Mechanisms of beam-plasma instabilities relative to the excitation of electrostatic and electromagnetic waves are considered during the electron beam injection (~10 keV, 0.1 A) from the Intercosmos-25 station. Development of transverse instability on the first cyclotron resonance leads to the excitation of whistler mode waves backward-propagating relative to the injected electrons (from the Earth). The investigation object was the beam-excited differential fluxes of ionospheric electrons in a wide energetic range of 27 eV — 412 keV registered by the charged particle spectrometers onboard the Magion-3 subsatellite. Thereby, the interaction of whistler waves with ionospheric electron fluxes is stimulated by the energy transfer mechanisms such as 'particle-wave-particle'. Numerical results of beam-plasma instabilities are compared also with thermal plasma parameters registered at different space points on the station and subsatellite. Excitation of longitudinal and transverse beam-plasma instabilities will inevitably lead to their competition, which will affect the results of the experiment. The data of stimulated fluxes of ionospheric electrons allow us to investigate the various effects of the wave-particle interaction, taking into account the influence of the growth rate of longitudinal instability on the excitation angle of whistlers and their structure. This approach is based on the results of laboratory experiments to determine the pattern of excited whistlers for an electric dipole antenna and the analogy of the beam-plasma channel with the radiating system. The results of the active space experiment confirm the dependence of the growth rate of whistler mode waves on the development of longitudinal beam instability.
