In Readme of TestEm5 :
5- TRACKING One can also limit 'by hand' the step lenght of the particle. As an example, this limitation is implemented as a 'full' process : see StepMax class and its Messenger. The 'StepMax process' is registered in PhysicsList::AddStepMax()
Follow TestEm5 to implement your own StepMax process. And, in StepMax::PostStepGetPhysicalInteractionLength(), do what you want.
