Electron Attenuation in Matter

Click For Summary
SUMMARY

The discussion centers on the search for electron attenuation lengths and cross-sections in matter, specifically for electrons moving through various solids. Participants mention the Bethe-Bloch equation as a potential tool for calculating energy loss as a function of distance, although its current applicability is questioned. The conversation also highlights the need for specific data, such as elastic and inelastic mean free paths, which depend on the initial energy of the electrons. Resources like the CRC Handbook are suggested as potential references for this information.

PREREQUISITES
  • Understanding of electron attenuation lengths
  • Familiarity with the Bethe-Bloch equation
  • Knowledge of elastic and inelastic mean free paths
  • Basic principles of particle physics
NEXT STEPS
  • Research the Bethe-Bloch equation and its applications in calculating energy loss for electrons
  • Explore the CRC Handbook for tables of electron attenuation lengths
  • Study the concepts of elastic and inelastic mean free paths in various materials
  • Investigate the relationship between electron energy and attenuation properties in solids
USEFUL FOR

Physicists, materials scientists, and researchers involved in particle physics or radiation studies will benefit from this discussion, particularly those seeking to understand electron interactions in matter.

Hi everybody,
I was wondering if somebody could help me find a chart or a table with electron attenuation lenghts or cross-sections in matter. I've searched the Internet inside-out but even if I would find something, it would be articles that you have to pay for :cry:. Still it seems a normal and trivial information to find somewhere. So if somebody has a handbook or something with that information - please let me know. Thanks a lot.
Mike.

Perhaps you need the bethe bloch equation?
Not sure how useful it is for electrons.
i don't know if its still used but as i recall it allows you to adjust certain constants that are typical of the soild you are using and calculate the the velocity damping. (or at least the energy loss as a function of distance) You could maybe use it to calculate something yourself.
Or do you need much data or already publsihed results to compare to?

Is the CRC a possibility?

I don't quite understand what it is that you're looking for. Are you looking for (1) the elastic mean free path, and/or (2) the inelastic mean free path of electrons moving in various solids? If you are, then you do know that in many cases, these values are dependent on the initial energy of the electrons, don't you?
