I need to make a detector like that in the left diagram of the attached png file which shows its aerial view. I made a group of G4Trd objects of the same material through rotation like that in the right diagram of the same png, but it didnít turn out to be equivalent to the left diagram in reality. I realized that the particle tracks need to move through a boundary defined by two G4Trd objects. I donít need this. I saw from the User Guide I may be able to use G4MultiUnion but I have Geant 4 ver. 10.00.p04 which doesnít have G4MultiUnion.
