On-ground calibration highlights for the SVOM/ECLAIRs camera

The Chinese-French mission SVOM due to be launched in 2023 is the next generation of missions fully dedicated to the survey of the transient sky thanks to an agile spacecraft embarking a multi-wavelength science payload associated with a network of ground robotic nIR/optical telescopes. The SVOM core instrument is the 4–150 keV 2-D coded mask camera ECLAIRs responsible for the autonomous search and trigger of transient events within its field of view. The flight model of ECLAIRs has been built by several French labs (IRAP, CEA, APC) under the supervision of the French Space Agency (CNES). In 2021, intensive on-ground calibration has been performed on the ECLAIRs camera. Here, we give an overview of the calibration sequences of the ECLAIRs flight model and we present an overview of the main instrument performances.
