The urgency and problems of instrumental studies of the density and composition of the upper atmosphere (ionosphere) are shown, which consist in the absence of instrumental means of direct measurements of the composition electron-ion trap combined density sensor of the atmosphere at altitudes from 150 to 500 km. In this article describes the possible design and study of the electron-ion trap combined density sensor and the composition of the upper atmosphere and simulation of the processes occurring in it. The simulation of the electric field between the electrodes of the trap and the motion of charged particles in it is carried out. The calculation of the maximum speed and energy of the particles, which the trap holds all charged particles, even in the case of the most unfavourable direction of their speed – along the gap between the electrodes. It is shown that this critical energy does not depend on the particle mass, and the probability of passage of charged particles with energy above the critical energy through the trap is estimated.
