None overlapping lots of events 

Forum: Event and Track Management
Date: 09 Jun, 2008
From: Cristian Bungau <Cristian Bungau>


In Geant4 usually an event is generated after the previous event has come to an end, however, in order to reproduce what is really happening, I have to generate (many) new events while the first event is still being processed and the isotopes produced in the first event have not decayed yet. This is because secondaries generated in the following events have to interact with the isotopes that are produced in the first event.

However in my code the second event is generated only after the first event isotopes have all decayed and therefore there is no interaction between the second event secondaries and the first event isotopes...

I was wondering what would be the best way to generate lots of new events (~1e6) while the first event is still being processed, so secondaries in the new events will interact with isotopes in previous events. Would multiple sources work? I would probably need about 1e6 multiple sources...

Or do I have to change the material on an event by event basis?

Thank you,
