Adriana, just curious, are you trying to simulate surface muons from a graphite production target?

Certainly, you can use StackingAction and reject immediately muons you are not interested in. You can also, at that point, reject any other secondary particle which cannot eventually produce a muon of interest. You have to be careful though, because muons are produced somewhere inside your target and may lose just the right amount of energy on their way out to make it into your energy range of interest.

This will certainly speed up your simulation. You'll still spend a lot of time simulating 10**13 protons. If you are interested in surface muons which come from pion decay at rest near the surface of the production target, I have employed a biasing technique which allows me to obtain the correct muon energy spectral distribution but I lose any knowledge of normalization/rate.
