17.  Function  Parameters  Beam Energy 800 eV to 9000 eV  Absorption Length: 10 microns to 100 microns  Attenuation factor: 10 microns to 100 microns  Geometry

18.  What is attenuation length/coefficient?  What is a k-edge and how can that help?

19.  Intensity: where I is the intensity of the photon beam, α is the linear attenuation coefficient, x is the path length  Transmission: Beer-Lambert Law
