Question GPS with multiple volume sources 

Keywords: G4generalparticlesource

From: Alain Ferragut <>

Hi, I would need some hints for using the new version of gps. I was used to the old version and therefore, I need to change my codes. My question is related to the following : I have 2 volumes V1 and V2, which are 2 different cylindrical physical volumes described in my geometry. For each event, I would like to generate only one primary vertex, either in V1 or in V2, but not in both volumes. In addition, the probability of occurence for a vertex in volume V1 or V2 depends on the ratio V1/V1+V2. What are the methods (or commands) I can use in order to do this ? Another question : in gps documentation, what is the meaning of "source intensity" ?

Thank for your help ,
