I am working on extended example: extended/eventgenerator/exgps. I am trying to replicate the example macro at the end of the link:
but I want to use a spherical source radiating inwards, towards the SiO2 sphere at the center, not outwards. I am using the following macro:
/gps/pos/centre 0 0 0 cm
/gps/radius 6 cm
/gps/ene/min 2 MeV
/gps/ene/max 10 MeV
but the flux always seems to be directed outwards, either from the center of the SiO2 sphere or on the 6-cm-wide shell, depending on the combination of values assigned to:
but never towards the center of the setup, which is the wanted.
I followed the steps shown in thread: http://hypernews.slac.stanford.edu/HyperNews/geant4/get/space_app/79/2/1.html
but, still, the model does not cooperate.
Can someone help?
Thanks in advance,
Constantin Athanassas, NTUA.
