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.

|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
you seem to have two G4OpSurfaces and you get them confused:
G4OpticalSurface* OpALSurface = new G4OpticalSurface("ALSurface");
OpALSurface->SetType(dielectric_metal);// should be dielectric_metal
G4LogicalBorderSurface* ALSurface =new G4LogicalBorderSurface ("TubeTwoSurface",TubeTwo_phys,experimentalHall_phys,OpCrystalSurfaceTwo);
You only need ONE and you don't have to specify a ALAbsorption. Optical photons in G4 do not at all penetrate metal:
G4LogicalBorderSurface* ALSurface =new G4LogicalBorderSurface ("TubeTwoSurface",TubeTwo_phys,experimentalHall_phys,OpAlSurface);
