Instrument details
Acronym
PWE
Full name
Plasma Wave Experiment
Purpose
Measurement of the electric field and its oscillations along the satellite HEO cross the magnetosphere
Short description
Detailed description not yet available. Presumably, electrometer covering the dynamic range 0.1-1000 mV/m for oscillations in the frequency range from 1 Hz to 10 MHz
Background
Companion of the Magnetic field experiment (MGF) on ERG
Scanning Technique
Volumetric exploration of the magnetosphere as the satellite travels along the HEO with perigee 300 km and apogee 30,000 km whilst spinning at 1 round / 8 s
