and the examples in:

/examples/extended/optical

in particular, to start with, OpNovice (previously, /examples/novice/N06).

Unfortunately, for a G4 novice, devising a beam-splitter is more complicated.

G4 has no concept of 'intensity'. You specify the number of simulation histories, with beamOn, and the program simply executes them. You adjust the number of histories you want to simulate from:

Intensity = # beamOn/time-interval

Your Part I, beamOn, corresponds to some time-interval that only you know. The number of optical photons generated by those P1 beamOn #, become the P2 beamOn # and thus correspond to the same time-interval.
