The signal formation in total electron-yield (TEY) XAS has been modelled for keV absorption edges using a computationally fast Monte-Carlo algorithm for the simulation of the Auger electron trajectories. It is shown that a pure KLL Auger-yield model achieves good agreement with experimental data for the K-edge TEY attenuation in Al and Cu. Advantages of the Monte-Carlo simulation approach over empirical and analytical models for the TEY are pointed out.
