Panoramic Energy-Mass Ion Spectrometer for the Phobos-Grunt Mission

摘要

Corpuscular diagnostics plays an important role in the study of the solar wind and the magnetosphere of Earth and other planets. Its goal is the investigation of the velocity distribution functions of ions and electrons and the mass analysis of the ion component of plasma. The measurement of the energy distribution function must be carried out in a wide range of angles, namely ±30° for the solar wind and 2n for the planetary magnetospheres.
