Plasma Processes Caused by an Electron Beam Injected from a High Altitude Rocket Probe. Part 2: Studies of Beam-Plasma Discharge

摘要

Electron beam interaction with a high altitude rocket payload was studied. The spectral distribution and intensity of the HF-field, glow intensity in the visible range, and the flux and distribution of electrons were used to identify beam-plasma discharge (BPD). In the initial phase of the experiment, local BPD is detected during beam-electron interaction with the intrinsic atmosphere of the payload (outgassing). Critical injection currents for BPD occurrence and a hysteresis effect of BPD are established. During the downleg, BPD formation in the natural atmosphere extends 100 m, decreasing during the payload's descent. The BPD effect on the neutralization of the rocket potential, formed during the injection, is discussed.
