HEPD-02<\/strong> (High Energy Particle Detector -02) and EFD-02<\/strong> (Electric Field Detector -02) are now in China<\/strong> following an extensive campaign of environmental tests and calibrations, which have successfully resulted in the qualification of both instruments at the end of 2023.<\/p>\r\n

Part of the team involved in Limadou Collaboration<\/strong> has been working in Beijing since early January to perform initial functional tests after payload integration into the CSES-02 satellite. Test results are consistent with expectations and mark the first winning post towards mission launch, planned for late 2024.<\/p>\r\n

HEPD-02<\/strong> is an all-Italian advanced particle detector. Its precursor – HEPD-01 – is mounted to the CSES-01 satellite, launched in Feb 2018. HEPD-02 will keep measuring flux variations for particles trapped in the Van Allen belts (electrons: 3-100 MeV; protons: 30-200 MeV), which are occasionally subject to precipitation to the atmosphere due to perturbations induced by solar, seismic and anthropogenic phenomena.<\/p>\r\n

Also EFD-02<\/strong> has been designed and built in Italy. This detector comprises the control electronics for four probes placed at the ends of as many 4.5-m booms produced in China. EFD-02 is meant for returning the three components of the local electric field by means of measurements in the DC\/ULF, ELF, VLF, and HF frequency bands with a sensitivity in the order of microV\/m, which represents the state of the art for ionospheric observations.<\/p>\r\n

In addition to Italian instrumentation, CSES-02 will accommodate nine state-of-the-art detectors designed for the simultaneous and continuous monitoring of major parameters suitable for the study of magnetosphere-ionosphere-lithosphere coupling, ionospheric structure and dynamics, and temporal variations in the geomagnetic field. Research on further key topics – such as the study of solar modulation of cosmic rays, Van Allen belts, and SEP emissions (i.e., space weather) – will be at hand as well. Indeed, the outer layers of our planetary envelope can be considered as a global, large-scale sensor of astrophysical signals: one major example was the CSES-01 observation of the 2022 gamma ray burst 221009A (BOAT), for the first time achieved via the monitoring of the ionospheric electric field.<\/p>\r\n

Any CSES mission is part of a collaboration program between the China National Space Administration (CNSA) and the Italian Space Agency (ASI). The Limadou Collaboration involves INFN (Divisions of Bologna, Naples; Rome Tor Vergata, and Turin; the Trento Institute for Fundamental Physics and Applications, TIFPA; and Frascati National Labs) as ASI’s major partner; as well as INAF-IAPS (Institute of Astrophysics and Space Planetology); the Universities of Bologna, Rome Tor Vergata, Turin, Trento, and UniNettuno Rome; INGV (National Institute of Geophysics and Volcanology); and CNR-IFSC (“Nello Carrara” Institute of Applied Physics).<\/p>\r\n
