I have low energy protons that have kinetic energy in the range of 5-6 keV that I wish to simulate in different detector materials such as Si etc. Up till now, I have used SRIM for that purpose, however I was wondering if there is a Geant4 based physics model which can accurately describe the interaction of such protons in matter. I am mainly looking for de/dx, tracking etc. to see how much of a signal these protons leave in a said material or if they are backscattered.
Any information would be highly appreciated.
