TARANIS (Tool for the Analysis of RAdiation from lightNIng and Sprites) is a CNES microsatellite dedicated to the study of magnetosphere-ionosphere-atmosphere coupling via transient processes. The TARANIS mission has four main objectives: estimation of the rate of occurrence of TLEs and associated emissions, identification of triggering actors, characterization of TGFs and accelerated runaway electrons from the atmosphere to the magnetosphere, identification of the effects of TLEs and TGFs on the coupling between the ionosphere and the magnetosphere, identification of the role of precipitated electrons in the coupling between the magnetosphere and the atmosphere.

Technical involvement

IRAP is responsible for the supply of the IDEE energy electron detector including:

  • Silicon and CdTe sensors that have been specially developed for the instrument by subcontractors. IRAP carried out the design optimization of the CdTe sensors in close collaboration with the manufacturer and defined and carried out the mechanical and thermal qualification.
  • An ASIC front end developed at IRAP. This ASIC includes 5 Silicon detection chains and 8 CdTe, which include ADCs. It has been extensively tested and optimized to meet scientific requirements.
  • One FPGA board and one high voltage board
  • A converter board that includes an original ASIC latchup protection circuit.
