Question Howto make G4Track information persistent? 

Keywords: G4Track
Forum: Event and Track Management
Date: 06 Aug, 2003
From: Mark Polsen <>

My detector geometry has a tracker and calorimeter as sensitive volumes for recording hit information. I would like to be able to store G4Track information on interactions only in sensitive volumes. For example, when an electron is created in my tracker from a Compton interaction, I want to store the position, energy, momentum, ... of the parent particle that created the electron.

I've noticed in the Developer Guide that G4Track is a transient class and that I can make my own Tracjectory class for persistency. After looking through the Geant4 code, I'm not sure if I should use the G4VTrajectory or G4VUserTrackinformation for storing my track info.

Once my track information is stored, how can I access it at the end of the event?

Thanks in advance!
