SUMMARY

The discussion focuses on calculating the Bremsstrahlung background for Transmission Electron Microscopy Energy Dispersive X-ray (TEM EDX) spectra. The original poster mentions the Kramers/Small formula, which exhibits a 1/E dependency that becomes problematic near zero energy. The inquiry specifically targets the Oxygen peak in the spectra, seeking alternative methods or references for accurate background calculation. Ultimately, the poster indicates that the issue has been resolved.

PREREQUISITES
  • Understanding of Bremsstrahlung radiation principles
  • Familiarity with Transmission Electron Microscopy (TEM) techniques
  • Knowledge of Energy Dispersive X-ray Spectroscopy (EDX) analysis
  • Basic grasp of spectral analysis and background subtraction methods
NEXT STEPS
  • Research alternative formulas for Bremsstrahlung background calculation in TEM EDX
  • Explore advanced techniques for background subtraction in EDX spectra
  • Study the impact of energy resolution on EDX peak analysis
  • Review relevant academic papers on Bremsstrahlung effects in electron microscopy
USEFUL FOR

Researchers in materials science, physicists working with electron microscopy, and analysts interpreting EDX spectra who require accurate background calculations for element detection.

Hi everybody,

first I like to thank you for this nice forum :smile:
I tried the search function and found no answer to my question, so here it is:
How can I calculate the Bremsstrahlungs background for TEM EDX spectras (Intensity vs. Energy)?
I found several formulas, for example the oldest Kramers/Small, but they all have
a 1/E dependecy, which of course go to ∞ approaching 0. But since I am interested in
the Oxygen peak, that doesn´t help much...
If anyone have an idea or can give me some directions (link to a paper maybe?)
I would really appreciate.

Thanks
