    "abstract": "We have simulated the performances of a GEM with a large density of\nmultiplication holes. In particular in this note we fully simulate the GEM\ndetector used in the PixiE experiment. The detector will be employed in the\nmeasurement of the polarization of X-rays produced by astrophysical sources and\nits optimization is critical. In particular we have studied the gain of the GEM\nand the diffusion of the charge inside the detector for different\nconfigurations of electric fields and for different gas mixtures. This study\nhas been performed to finalize the design of the PixiE Imager Detector.",
