DESCRIPTION:Speakers: Coralie Neubüser (Hamburg U.)\n\nAbstract: The Chi
 na Seismo-Electromagnetic Satellite (CSES) missions represent the forefron
 t of space-based efforts to study the coupling between the ionosphere and 
 lithosphere. Equipped with a diverse array of instruments\, these missions
  can detect a broad range of perturbations in the ionosphere and magnetosp
 here\, including transient electromagnetic emissions (e.g.\, from lightnin
 g) and long-duration particle injections resulting from space weather even
 ts. The first satellite was launched in August 2018\, and in this presenta
 tion\, I will highlight some of the key scientific findings obtained so fa
 r. One of the principal instruments aboard CSES is the High-Energy Partic
 le Detector (HEPD)\, which monitors electrons and protons with energy thre
 sholds of 3 MeV and 30 MeV\, respectively. The Limadou collaboration has d
 eveloped an improved version of the HEPD for the second satellite in the C
 SES constellation\, launched in June 2025. A significant upgrade is the us
 e of Monolithic Active Pixel Sensors (MAPS) for the tracker\, a technology
  never previously used in space. Compared to conventional hybrid silicon m
 icrostrip technology\, MAPS offer improved precision\, robustness\, easier
  control and readout\, reduced costs\, and less invasiveness. However\, MA
 PS still face challenges\, such as small size and higher power consumption
 . The HEPD-02 tracker will consist of 150 ALPIDE sensors\, with a custom-d
 esigned operation mode and readout system tailored for space applications.
  The flight model of HEPD-02 underwent extensive test-beam campaigns in 20
 23\, and I will present the first performance results from these tests.
