[Gate-users] msc and eioni processes

[Marc Verderi]

Hi Anayisse,

The "msc", or the multiple scattering, is a process for charged 
particles. It computes the change of energy and direction due to -as 
said by the process name- multiple scattering on nuclei. The Compton 
process is for photons, it simulates the production of electrons when a 
photon "bounces" onto an electron, communicating it a substantial 
fraction of its energy, large enough to have this electron travelling 
far from its original atom.

These processes can be disabled (but I don't know if Gate provides some 
layer on top of Geant4 to do it). Why would you want to disable them ?
