Question Energy deposited step by step 

Forum: Event and Track Management
Date: 26 Mar, 2014
From: Manuel Castro Avila <Manuel Castro Avila>


I am working with the simulation of the behaviour of a satellite in a space environment where some particle's fields like protons, electrons, neutrons or photons interacts with the instruments on board.

I am interesting in the energy deposited by the particles when move through different volumes until search the detector. Checking the Geant4 documentation, I understand that every particle when interact is represented by a G4Track class where the primary has TrackID=1 and ParentID=0, am I right? Now, if the primary generates a new particle, this particle has a TrackID>1 and ParentID=1 because was generared by a particle with TrackID=1?

In order to get the energy deposited, I use the G4Step class to get it (that evolves step by step until the particle tracking finish), but if a check the static particle attributes of that track, some times the energy deposited is due to the primary particle and some times due to secondaries. I don't understand very well how it work..? For example, when gamma photons interact with a material, some times the energy deposited is due to the gamma photon and some times due to electrons, I know that photons when interact produce electrons, but I don't understand what mean when Geant4 shows that energy deposited is due to photons (some tracks) and some times is due to electrons...?

Thanks in advance,
