When I studied this tutorial: http://geant4.slac.stanford.edu/SLACTutorial09/HandsOn4/
the detector of this example is a Sensitive Detector constructed by parameterised volume, there is only 1 primary particule in PrimaryGeneratorAction class, When I run the program with /run/BeamOn 20 in the macro file, it will give 20 simulation results with 1 primary for each simulation.
To launch more than 1 primary particle for each run (for this example), I have to give a number which is superior to 1 in PrimaryGeneratorAction class (for example 100) and reduce BeamOn to 1. Otherwise, it will perform 20 simulations with 100 primary by simulation.
But what I would like to do is to gun n(with n = a very high number) particle by specifying it in the macro file because I want a different random number for each event as the PrimaryGeneratorAction class is called with the same number of the events.
Could someone tell me what I have to do ?
Thanks in advance.
