STGM mother volume is a tube, with half-z = 200cm, radius = 300 cm (inner 5.9 cm). Positioned once at z=300 cm. So there will be overlaps with other objects in the geometry. STGM should be placed as konly="MANY".

Also, recommend declaring it as an assembly, and setting attributes.

<Volume STGM assembly="True" comment=" ... "> <Material name="Air" /> <Attribute for="STGM" seen="0" colo="1" /> <Shape type="tube" rmin="5.90" rmax="300.0" dz="200" />
