Miniaturized panoramic plasma analyzers
Miniaturized panoramic plasma analyzers

Function

Fast detailed measurements of velocity distributions of ions (with mass resolution) and electrons in the interplanetary medium, in the Earth’s magnetosphere, and in the planetary environments.

Description

Measurements of charged particles are performed simultaneously over a half-space of velocity directions at the fixed energy. Energy scan is performed within 0.1–1.0 s. The novel detection scheme includes electrostatic mirror system, time-of-flight mass-spectrometer (for ions), and position-sensitive detector.

The design is based on the experience of Interball and Mars-96 missions. Currently following new instruments are in development: PICAM for ESA’s Bepi-Colombo project, DI for Russian Phobos-Grunt project, IONCAM and ELCAM for Russian Resonance project.
