Hi all,
I am trying to calculate the penetration depth of a beam of electrons which have an energy of 12 keV. The target material is aluminium (for x-ray production).
Initially I tried doing calculations using a Beer's law type equation; however I got higher values then expected.. probably due to mass/linear attenuation coefficients being for x-rays themselves and not electron interactions.
So my question is... do I need to look at scattering cross sections (ionization cross sections?) for aluminium at 12 keV instead? If so could anyone provide a link where I could obtain this data?
If not; can somone point me in the right direction?
Many thanks for any assistance
