Use Conductive Coating Correction For Energy Loss

Toggle the correction for adjusting the electron beam energy for electron energy loss due to the conductive coating. Important when working at low overvoltages. Uses a modified equation from Kerrick et. al., Amer. Min. 58, 920-925 (1973) and Springer (1974).

 

' Intensity correction from electron energy loss due to coating

ratio! = (100# - ((8.3 * sample(1).CoatingDensity! * sample(1).CoatingThickness! / ANGPERNM&) / (sample(1).KilovoltsArray!(chan%) ^ 2 - (sample(1).LineEdge!(chan%) / EVPERKEV#) ^ 2))) / 100#

 

Note that the coating parameters for standards and unknowns are ignored in the quantitative calculations until the electron absorption and x-ray transmission coating correction flags are explicitly turned on from the Analytical | Analysis Options menu dialog.
