Figure 2
Linearity of sensitivity of C7942MOD. The data were obtained at BL40XU with an X-ray energy of 15.0 keV. Aluminium absorbers (0.4 mm thick) were inserted into the beam to attenuate the intensity stepwise. The intensities at four different pixels, after background subtraction, are plotted. In the ordinate, the unity of intensity was that without an absorber. For all the sets of data, the R2 value of regression was larger than 0.9999, and the y-intercept was within 10 of the origin (the data for the regression do not include a value at the origin). |
