摘要

The Electric Propulsion Electrostatic Analyzer Experiment is the most recent iteration in a series of laminated electrostatic analyzers that have flown in space. The sensor functions as an ion energy bandpass filter for space plasma, from which the ambient ion density, temperature, and subsequent spacecraft frame charge can be obtained. We present the ÉPÉÉ instrument design and initial on-orbit cross-calibration with the Floating Potential Measurement Unit. The calibrated data are then used to provide observations of the mid-latitude ionosphere during the geomagnetic storms that occurred on November 4th and 5th in 2023.
