Abstract: An X-ray detector based on the combination of an integrated Micromegas stage with apixel chip has been built in order to be installed at the CERN Axion Solar Telescope.Due to its high granularity and spatial resolution this detector allows for a topologicalbackground suppression along with a detection threshold below 1 keV.Tests at the CAST Detector Lab show the detector’s ability to detect X-ray photons downto an energy as low as 277 eV. The first background data taken after the installation atthe CAST experiment underline the detector’s performance with an average backgroundrate of 5 × 10$^{−5}$ /keV/cm$^2$/s between 2 and 10 keV when using a lead shielding.
