Figure 7
Dependence of the measured step on the expected beam position using different pixel clusters at 120 keV. The measured steps can be inferred from Fig. 1[link], where the first measured step along the x direction and its error bar are the mean and standard deviation of the following steps: (1 to 2), (9 to 10), (17 to 18), (25 to 26), (33 to 34), (41 to 42), (49 to 50) and (57 to 58). Similarly, the second measured step and its error bar are the mean and standard deviation of the following steps: (2 to 3), (10 to 11), (18 to 19), (26 to 27), (34 to 35), (42 to 43), (50 to 51) and (58 to 59). The x-axis represents the expected position of the beam inside the pixel where position 0 µm is the pixel edge (pixel start) and 27.5 µm is the pixel center.
