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.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|

There are several things not right with this code. I suggest you reduce your geometry at first to just one volume (tracker_phys) and then add your plastic shell, Al housing, one at a time. You should also define the corresponding surfaces as you build up your geometry in these steps.
For one, you give the experimentalHall_log a G4LogicalSkinSurface. This cannot work because there is no 'outside' to your world (experimentalHall_log) and I don't think you intended to do this (have photons bounce around inside your world).
Also, yes, the material "Air" has no index of refraction. Moreover, there is something wrong with how you built your geometry. It seems to me, a thin glass disk is placed in experimentalHall where there already is the tracker_phys. This produces an volume overlap not allowed in G4.
