I am trying to build a cylindrical source confined in a Physical Volume. Upon running the below macro it seems that although my particles are emerging randomly from various locations, they are mostly concentrated in the center, I have attached a figure of /run/beamOn 500, Let me know if this looks normal. I want the particles to be generated in the entire geometry with an equal spacial distribution.
