Postshower design

Postshower with two halves and top trapezoidal section.
The edges are projected from the shower max position in the center of the inner- and outermost towers in the FMS.
Inner edge: 23 cm
Outer edge: 108 cm

All scintillators will need an additional 1 cm block and 6 cm pyramid light guide to connect to the SiPM readout on the outside (left, right, top, bottom) of the detector.

Layers 1 and 2 each use just one size of scintillator slats.
Layer 3 uses seven different scintillator sizes.
Layer A uses the same scintillators as layer 1 (rotated).
Layers B and C use the same scintiilator sizes as layer C (and possibly one additional smaller size).

Positions and scintillator types are listed in the attached geometry.txt file.





(This is a 3d view; the outer edges of all layers are in fact aligned.)
