The medium-energy electron detector on board CSES-02

The medium-energy electron detector on board 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 the technical means for exploring new technologies and methods for earthquake monitoring and prediction. This work presents a description of the scientific objectives, key technical specifications, payload design, and results of ground calibration and verification for the payload.
