Abstract

Abstract The paper presents some results obtained when a beam of electrons (energy 2 to 3.5 keV, current 0.2 to 0.4A) was injected from aboard the rocket at 100 to 150 km. At the moments the beam was injected perturbations of the near-rocket region are observed with a cross-section of about 500 m, it is much larger than the region over which the injected beam is extended. The appearance of the above region can be explained by the interaction of accelerated ions with the surroundings; the ions are generated during the positive rocket charge neutralization owing to discharge mechanisms. It is confirmed by direct measurements of the rocket potential which is about 2 kV near the apogee.
