Plasma particle spectrometers for space missions

Plasma particle spectrometers for space missions

Function

Measurements of energy-angle spectra of charged particle fluxes in various energy and density ranges in the ionospheric, magnetospheric and interplanetary plasmas for:

investigation of Earth’s magnetosphere, interplanetary space and planetary plasma environments;
monitoring of near-Earth space in the interests of space weather applications.

Description

Omni-directional hot plasma top-hat analyzer with instantaneous FOV 360õ7°.
Omni-directional cold plasma detector with six wide-FOV Faraday cups.
Energetic ion, electron and heavy nuclii spectrometer with semiconductor detectors.
Low energy interplanetary plasma spectrometer with 8 angular channels.

Currently instruments are developed for Russian scientific space projects Resonance, Interheliozond and others. Energy and angular resolution depends on the project goals and determines the number of detector units to be used.
