  1- GEOMETRY DEFINITION
 
      The geometry consists of a cylinder of homegenous material.
-     This cylinder is replicated longitudinaly (slice) and radialy (ring).
 
      The default geometry is constructed in DetectorConstruction class,
      but all of the above parameters can be modified interactively via

+     The cylinder is virtually sliced longitudinaly (slice) and radialy (ring).
      The size of the slices and rings are expressed in radiation length units
