I've attached an EventAction.cc and an illustration of my 20cm water-bone phantom. The DetectorConstruction.cc gives a full detail of my phantom construction.
Every 0.5 cm along the z-axis of the phantom, there is a water sensitive volume of 0.01 cm. The upperhalf bone width is 1 cm located at z= 18cm. I want to place a lowerhalf water sensitive volume right underneath that upperhalf bone. That lowerhalf water will have a 1cm width. So I created a new class of LowerWater. The problem is in the EventAction.cc (i.e. "under void EventAction::EndOfEventAction(const G4Event* )"), I need to declare:
THIS lateral=lowerwater_lat_in; lateral=lowerwater_lat_out;
AND THAT lateral=bone_lat_in; lateral=bone_lat_out;
direction=bone_dir_in; direction=bone_dir_out; At the same time, Because the upperhalf bone and lowerhalf water are located at the same z= 18cm. They cannot share the same indices. How do I go around that?
