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
