Expected counts as a function of a threshold energy for a monochromatic beam of energy E0 = 12 keV. N0 = 10000 is the number of photons absorbed by the detector during the acquisition time. The dashed line represents the curve in an ideal case without electronic noise and charge sharing, the solid thin line with noise ENC = 1 keV but without charge sharing, and the solid thick line is the physical case with noise and charge sharing Cs = 22%. NS is the number of photons whose charge is shared between neighbouring strips (Cs = NS/N0). The dotted line represents the number of photons whose charge is completely collected by a single strip. |
