The following tables show the number of escapes for each area ΔA_i and different energies. Each escape is an electron which starts from the center of the area ΔA_i, makes its way out of the chamber of the telescope and reaches the aperture. The electron might not have any impact with the wall of the telescope, but if the electron hits the wall we assume the electron has a single elastic specular backscattering with the wall and continues its trajectory until it hits the wall (terminated) or the aperture (escape). The probability of the backscattering is determined by the energy, atomic number of the target and the incident angle of the electron. The probability formula is based on Radzimski's formula (see also section A10.7). For each area ΔA_i an electron runs every δθ = 2º and δΦ = 5º and exhausts all possible polar θ and azimuth Φ angles.
