0040       ### Forward (Positive Z) Endcap Insert for Electromagnetic Calorimeter
0041       Insert goes in the middle of the forward endcap ECal -- around the beampipe
0042
0043       Has 5 sections:
0044         - Aluminum cover
0045         - Air gap
0046         - PCB
0047         - Light guides (plexiglass)
0048         - Scintillating fibers (modeled as homogeneous material)
0049
0050       Circular hole is cut out from each layer to account for the beampipe
0051       Hole radius is beampipe radius + 3.85 cm of clearance
