Characterization and performance optimization of the focal plane of the Micro-channel X-ray Telescope on-board the space astronomy mission SVOM

Abstract : SVOM is a Chinese-French astronomy mission due to launch at the end of 2021 for the study of Gamma-Ray Bursts (GRBs). SVOM will be composed of a network of ground telescopes along with a satellite. On board, the Micro-channel X-ray Telescope (MXT) will study the afterglow emission of GRBs in the 0.2-10 keV range and provide source localization within a 2 arcmin precision. At the focal plane of lobster-eye optics, MXT will mount a back-illuminated fully-depleted frame-store Charge Coupled Device based on silicon pn-junctions (pnCCD), heritage of XMM-Newton and eROSITA. In this work, the first laboratory tests on the MXT detector are presented. Special attention is dedicated to energy calibration, in terms of algorithms and setups for fast and reliable characterization of the detector, both on ground and in orbit. The evolution of the performance is of critical concern because of the harsh radiation environment of the low Earth orbit to which the detector will be exposed. This is the object of extensive Monte Carlo simulations, leading to predictions of the end-of-life performances as well as the planning of a proton irradiation campaign at a particle accelerator for the experimental validation of the predictions.
