Figure 5
Pulse height distribution of the integrated APD single pulse intensity for 10⁵ X-ray pulses (black dots). A mean flux of 80 photons per pulse is derived, when scaling the measured signal to the values as derived in Fig. 4

. A Poisson function with I_TFY = 80 (blue solid line) and Gaussian fit to the data with σ = 11 (red dashed line) are shown for comparison.
