Energy Distribution of Ions and Electrons

NSSDCA ID: 1974-055A-02

Mission Name: Aeros-B
Principal Investigator:Dr. Karl Spenner


A retarding potential analyzer measured the energy distribution of electrons and ions. The corresponding temperatures were derived from these distributions. The experiment operated in an electron mode and in an ion mode. The instrument was essentially a collector, shielded by parallel plane grids. By sweeping the retarding voltage of the grid, the energy spectra of the ionospheric charged particles were obtained. The particles only passed through the grid and reached the collector if their kinetic energy exceeded the retarding potential.
