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.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

I gather from a private email you sent me that you have now understood the geometry and that the glass is simply a layer between the photo-cathode and your scintillator volume (entrance-window).
As for your second question, I assume you've modeled your code following the LXe example and you therefore have a ProcessHits_constStep method which triggers a G4-Hit when the photon hits your photo-cathode. In order for you to find the local coordinates of the point where the photon hits the cathode, you'll need code provided in the wls-example; specifically:
G4ThreeVector photonArrive = thePostPoint -> GetPosition();
G4TouchableHistory* theTouchable = (G4TouchableHistory*)(thePostPoint->GetTouchable());
// Convert the global coordinate for arriving photons into // the local coordinate of the detector
photonArrive = theTouchable->GetHistory()-> GetTopTransform().TransformPoint(photonArrive);
Please, do your research - for example, the answer to your question can be found at:
