Question Physics for Beamdump-simulations 

Forum: Physics List
Date: 15 Oct, 2010
From: <kram@kph.uni-mainz.de>

Dear Simulanten,

we try to to simulate the background coming from some beamdump to our detector. We have 500MeV positrons incident to the beamdump. From the discussions, I would conclude that the physics list QGSP_BERT_HP is a good start, although we are in the "low-energy regime". Is this right?

But to understand in more detail what happens, I would like to understand how this physics list is made up (from a programmers viewpoint) and what is included (from a physicists viewpoint). In addition I would like to switch on and off different contributions, for example neturons emitted from the dump.

Is there any documentation available which could help to understand the structure of the source-code and how to make up such lists and switch on/off or to exchange certain processes?

In addition I get Warnings like

NeutronHP: /Capture/ file for Z = 20, A = 48 is not found and NeutronHP will use /home/kram/geant4/data/G4NDL3.13/Capture///CrossSection/20_nat_Calciu

Is this something to worry about?

Thank you very much in advance Dirk.
