The paper presents the results and discussion of VLF wave measurements carried out in the course of two rocket experiments on injection of a dense cesium ion beam into the ionosphere at the heights of 165–240 km. The injection was accompanied by enhancement of the broad-band noise by several orders of magnitude. The wave measurements in the frequency range of 1–11 kHz revealed two pronounced frequencies somewhat exceeding that of the lower-hybrid resonance oscillations in the background plasma and the cesium beam. The oscillations were modulated by frequencies close to the ion-cyclotron frequencies of the background plasma. 相似文献

The results of measurements made by the retarding potential analyzer of electron fluxes recorded during electron beam injection ~0.5A current pulses and energy 15 or 27 keV during the ARAKS experiment are analyzed. The relatively low rocket potential (~150 V) observed is explained by the formation of a highly conducting region near the rocket. Such a region can be formed via intense plasma waves generated by the beam. This mechanism also explains the heating of the electrons near the rocket. Measurements of electron fluxes with energies of 1 to 3 keV and estimate based on the beam plasma discharge theory agree very well. 相似文献

It is shown that experiments with geostationary injections of dense barium plasma clouds after CRRES program presented a unique opportunity for investigation of Earth's space environment radiation generation mechanism at frequencies 100 to1000 times higher than the usual plasma frequency signal. We present electromagnetic noise or radiostorm data obtained in Havana in broad frequency bands 45–90 MHz, 235MHz and 280 MHz after Ba injection. It is proposed that signals appearing with 7 to 10 min delay after injection possibly caused a substorm initiated by the injection, during which the radiation is generated by local energetic particles flowing through the irregular barium cloud. Another possibility is connected with irradiation of the barium cloud by the Jicamarca radar. Modulation of radioburst at barium gyrofrequency is typical for both cases. 相似文献
