Kurzfassung

An X-ray detector based on the combination of an integrated Micromegas stage with a pixel 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 topological background suppression along with a detection threshold below 1keV. Tests at the CAST Detector Lab show the detector's ability to detect X-ray photons down to an energy as low as 277eV. The first background data taken after the installation at the CAST experiment underline the detector's performance with an average background rate of 5×10−5/keV/cm2/s between 2 and 10keV when using a lead shielding.
