Dear Marc,

Right now I am just making tests. Finally I need 10^8 protons/electrons per second, so for a good start is good to make tests with small number of particles. The G4CoulombScattering is indeed very precisely but I have got to much events->steps, G4MultipleScattering 2 steps. With electrons and with multiple scattering I have got 30 steps for 8 mu m AL foil. Which is very good from computing time point of view.

I have got an email form Mr Weller, which makes a suggestion to use G4ScreenedNuclearRecoil with G4MultipleScatering (the example TestEm7). The results are of course physically but in that case I have got 30 events. Which is a good solution for my problem. I want to point this information for future readers.

Best regards, Maciej
