I've browsed through the forum and found some other posts which address the same problem I am having.

* "Characteristic line production rates" by Stephen McMahon (posted on Sept 2008)

* "Low characteristic x-ray production" by Daniel Bonifacio (posted on Nov 2004)

[Also: MONTE CARLO SIMULATION OF X-RAY SPECTRA IN DIAGNOSTIC RADIOLOGY AND MAMMOGRAPHY USING GEANT4, D. Bonifacio et al., http://www.ipen.br/biblioteca/2005/inac/10687.pdf]

I have downloaded and installed the latest available version of GEANT4 (i.e. v9.3-beta01) and am using the most up to data low energy library (i.e. v6.5). Further, I have read about the changes to the LowEnergy models and that they have been migrated/renamed to the Livermore physics models (https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigratedLivermore). So, in the latest version of my simulation code I am using the G4Livermore... equivalents of the G4LowEnergy... functions, but the results have not improved and the ratio characteristic X-rays to the Bremsstrahlung continuum is still too low.

Am I therefore to believe that these energies (i.e. <= 30 keV) are too low to be simulated with GEANT4 for my specific problem (transport of electrons and X-ray production)?

Any comments and/or suggestions are greatly appreciated!

Kind regards,

David
