ATLAS FP TRACKER PLANS. Steve Watts School of Physics and Astronomy University of Manchester. Well defined design in the FP420 Design Report Based on the FE-I3 ATLAS Pixel Readout chip. Design suitable for 220 but needs roughly double the number of

SOLUTION A 3D sensor safe to 1-2 1016 charged hadrons per cm2
Dose highest in very narrow vertical band.
Move sensors up and down by 1-2 mm to even out the dose
Trick used with CCDs in NA32. Additional specification for mechanical design.
Would give a factor 3.
Use FE-I4. Factor 5 more radiation tolerant than FE-I3. For IBL project
Plus - better matched to track hit distribution at 220.
- Common module design for 220 and 420 - 2 x Fe-I4 each plane
Chartered reticule (24 x 32)
NOTE2: Assumes hits distribution stable with time…..
