The approximate dose per bunch train was calculated as shown above. Io is the incident X-ray energy, g is the gain in units of ADU keV−1, Sd is the difference in output between illuminated and unilluminated integrations, μ is the mass absorption coefficient (taken here also to be roughly equivalent to the mass attenuation coefficient), A is the area of the pixel, and ρ is the density of silicon. This simplified calculation neglects absorption by, for example, solder bump-bonds.
