Abstract

The spatial distribution and dynamics of subrelativistic electron fluxes (from tens to hundreds of keV) were studied in a space experiment onboard the Vernov satellite. A joint analysis of the experimental data from the Vernov and POES satellites was carried out. Maps of the global distribution of electron fluxes with energies from hundreds keV to MeV in the near-Earth space were obtained, as well as their distribution over drift shells, local time, and geomagnetic longitude. It is shown that significant electron fluxes of subrelativistic energies exist in drift shells with a McIlwain parameter of L < 1.5. The measured longitudinal distribution of electron fluxes in these drift shells indicates that the observed fluxes are “tied” to the shells, and the inhomogeneities of the longitudinal distribution are caused by the features of the configuration of the magnetic field in the satellite orbits.

来自Vernov卫星数据的近地空间亚相对论电子通量的时空特征

摘要

在Vernov卫星上进行的一项空间实验中，研究了相对论性电子通量（从几十到几百keV）的空间分布和动力学。对来自Vernov和POES卫星的实验数据进行了联合分析。获得了近地空间中能量从几百keV到MeV的电子通量的全局分布图，以及它们在漂移壳，局部时间和地磁经度上的分布。结果表明，McIlwain参数为L的漂移壳中存在亚相对论能量的显着电子通量。<1.5。在这些漂移壳中测得的电子通量的纵向分布表明，观察到的通量“束缚”在壳上，并且纵向分布的不均匀性是由卫星轨道中磁场的结构特征引起的。
