Measurement of the density and the composition of the upper atmosphere by the Electron-Ion trap sensor

Abstract

Abstract This article explains the design of the electron-ion trap sensor for measuring the density and the composition of the upper atmosphere. The simulation of the electric field between the trap electrodes and the charged particles motion in it is carried out. The calculation of the maximum energy and speed of the particles below which the trap holds all charged particles, even in the case of the most unfavorable direction of their speed-along the gap between the electrodes. It is shown that this critical energy does not depend on the mass of the particle, and the probability of charged particles passage with an energy more than the critical energy through the trap is estimated [1].
