0075 ### Forward (Positive Z) Endcap Insert for Hadronic Calorimeter
0076 Insert goes in the middle of the forward endcap HCal -- around the beampipe
0077
0078 Insert is 60 layers of Steel/Sc + 1 backplate of steel
0079 Each of the layers (sans backplate) includes air gaps (front and back of each layer),
0080 ESR foil (front and back of scintillator), a PCB, and an aluminum scitnillator cover
0081
0082 Circular hole is cut out from each layer to account for the beampipe
0083 Hole will change in size and position throughout layers due to angled (from crossing angle) and cone-shaped beampipe
0084 Hole radius is beampipe radius + 3.85 cm of clearance

0138 Readout is segmented into hexagons with sides of 2.16 cm, 2.84 cm, and 3.10 cm in the high-granularity upstream section (layers 1-16, for both left and right sides),
0139 the left downstream section (layers 17-60), and the right downstream section (layers 17-60), respectively.
0140 The hexagons positions in the first 16 layers cycle through four sets of layer configurations ("H4 staggering")
0141 i.e. hexagons in layers 1-4 (5-8, ...) are all offset transversely from each other
0142 with the centers of the cells of one layer being at the midpoints of the edges of the cells in
0143 the other layers.
