In this paper the performance of a GaAs detector based on a pixel matrix architecture is experimentally evaluated. Several spectral distribution have been obtained for a single GaAs pixel and compared with that of a reference Si sample in order to determine the Charge Collection Efficiency and the Energetic Resolution. The obtained results indicate the detector ability to interact with low-energy X-ray to generate good quality images for high-contrast details
