The Medium-Energy Electron Detector on board CSES-02

The medium-energy electron detector on China's second earthquake monitoring satellite can measure the energy, flux, and direction of medium- and high energy electrons within the satellite's orbit. These data may provide technical means for exploring new technologies and methods for earthquake monitoring and prediction. This paper presents a description of the scientific objectives, key technical specifications, payload design, as well as the results of ground calibration and verification for the payload.
