I made a detector consisting of one adsorber and gap by replicating then throughout the volume in GEANT4. Now I want to place a single converter box in a particular gap. I have modified' Basic example B4'. But the problem is when I assigned another box, it has been replicating in all the gaps as its physical volume is replicated. Are there other ways to do it?
Hello.
Indeed when you add a daughter volume "D1" to a logical volume "L1", then it will appear inside all physical volume which are 'copies' of "L1", i.e. whose logical volume is "L1".
The answer is to create a second logical volume "L2" in which you will place the daughter volume "D1". Whereever you want "D1" to appear, you must create a physical volume using "L2" as the logical volume.
Note: it is best to ask your questions on the Geant4 User forum - at https://geant4-forum.web.cern.ch/
Thank you. I have successfully created as you said. This time I did not replicate the detector layers. Instead, I just placed them one by one. Finally, the single volume has been set according to its logical volume's copy number.
