CALs distances IMPORTANT NOTE:
1. Consider that each CsI crystals has a wrapper around 0.75mm thick.
...
DH=Hext - Hint=1.44mm --> wrapper thickness=0.72mm
2. At each crystal end there are both gap and endcap.
The gap+endcap length is around 6mm (the length is variable reffering to NLR drawings, link below)
...
DL=Lext - Lint=12mm --> gap+endcap length=6mm
