Detailed Description

A barrel layer (MagBLayer) groups volumes at the same distance to the origin. It consists of either 1 single volume (a cylinder) or 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.
