CALs distances IMPORTANT NOTE: 1 ).Consider that each CsI crystalscrystal has a wrapper around 0.75mm thick. This wrapper thickness must be subtracted to have the exact distances. Hext (CsI layer height)=21.34mm Hint (CsI crystal height)=19.9mm 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) Lext (CsI layer length)=338mm Lint (CsI crystal length)=226mm DL=Lext - Lint=12mm --> gap+endcap length=6mm.72mm 2. At each CsI crystal end there are both gap and endcap. Lext (CsI layer length)=338mm Lint (CsI crystal length)=226mm DL=Lext - Lint=12mm --> gap+endcap length=6mm |
