8. 3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June 2009 8 Modules & Stave Arrangement Two module options: Single chip modules abut one against the next Small sensor type: like 3D, active edge Multi chip modules: chip look the same if using multi-chip modules As present sensor size (~2xFE-I4) : like planar n-on-n assuming no Z-shingling, no space. W-bond pads

9. 3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June 2009 9 Requirements - Fluence Requirements discussed in previous meetings New simulation of n fluences as input for the IBL design (see box) Other requirements are: IBL design Peak Luminosity = 3x10 34, Integrated Luminosity seen by IBL = 550 fb -1 Fit made for 2 < r < 20 cm for L=1000fb -1 Gives for IBL @ 3.7 cm (550 fb -1 ): 1MeV =2.4x10 15 (1.2 MGy) Safety factors not included in the computation (pp event generator: 30%, damage factor for 1 MeV fluences: 50%) Ref.
