Detailed Description

A container of volumes in the barrel. It is part of the hierarchical organisation of barrel volumes:

A barrel layer (MagBLayer) groups volumes at the same distance to the origin. It consists of 12 sectors in phi (MagBSector). Each sector consists of one or more rods (MagBRods) of equal width in phi. Rods consist of one or more slabs (MagBSlab); each one consisting of one or, in few cases, several volumes with the same lenght in Z.
