Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Hi Mike, The G4VPhysicalVolume class has a copy number data member, which numbers the physical volumes within their mother logical volume. In general, the physical volume is unique only within its mother volume, as the mother volume can be also placed several times, so it is not possible to associate an integer identifier which would be unique in the whole geometry to a physical volume. You can find more complete explication in the Geant4 tutorials, eg. in: http://lappwiki01.in2p3.fr/Geant4-LAPP/index.php/Talks in the "Geometry 2" lecture, in the chapter "Touchables" (slide #16 - #21). We can give you more help if you describe how are your sensitive volumes organized in your detector. Best regards, Ivana
