** 3. SIDIS FAEC needs to move upsteam 85cm to become PVDIS FAEC, so the supporting structure needs to allow the movement. Note at the before and after locations, the endcap nose shape changes.

If the supporting is only connected to the endcap donut (15cm thick iron), not the endcap nose, it won't be a concern any more.

number of module

  • assume 100cm2 module area, calculate number of modules by module coverage, we get
    • PVDIS FAEC 1860
    • SIDIS total 1879
      • SIDIS FAEC 1464, SIDIS LAEC 415 (about 360 regular module, 55 small module)
  • ANL design hexagon layout for FAEC has module about 1750 [1]
  • So 1800 module in total is good guess

weight

assume 44 long and length ratio Pb:Sc=1:3 shower, 100*44*(0.75*1.032+0.25*11.34)=16kg

assume 2 radiation length lead 1.12cm and 2cm Sci preshower, 100*1.12*11.34+100*2*1.032=1.5kg

assume everything else, like wrapping, rod etc is about 2.5kg

total module weight about 20kg each
