Hello,

PAI model may be recommended for accurate simulation of relativistic protons. You may study

$G4INSTALL/examples/extended/electromagnetic/TestEm8

Concerning tracking of low-energy e- you need to know that ionization models produce secondary e- above threshold, shown in your e-mail. This threshold cannot be lower than mean ionization potential of the media. Electrons below this threshold are not produced and their energy is added to energy deposition at a step.
