Dear Sir, I re-send this question because I have not gotten any solution yet. Could you please forward the question to someone who has expreience in using GEANT4 to track low energy electrons (~10eV)? I am trying to track e- below 1 keV, for an example about 10eV. In order to do this, I set the cut off as 1.mm and 0.000001 mm for electrons, because the range for low energy electron is very small, but I did not get any electron below one keV in both cases. The initial energy of electron is 662 keV. Could you please show me how to get the tracking of electrons below 1.0 keV? Thanks, Yuxin
The current version of Geant4 Low Energy Electromagnetic Package has the capability to handle electrons correctly down to 250 eV. It is explained in the documentation that below this threshold the accuracy of the simulation cannot be guaranteed, and it is recommended not to use the current lowenergy electromagnetic processes below this limit. A new set of Low Energy Electromagnetic processes, specialised in the very low energy range down to a few electronvolts, is currently under development. They will be avilable in future Geant4 releases.
