Elements of an SLHC Tracker• < 20 cm: inner, dose:1016 /cm2

– new technology• 20 < r < 50 cm: intermediate, dose: 1014-1015 /cm2

– pixels, short strips, strip-pixels– modularity, mass, reliability, system issues– 60 m2, 4K “SCT modules”

• > 50 cm: outer 1012-1013 /cm2

– strips– modularity, mass, construction logistics – 140 m2, 16K “SCT modules”

Development of Tracking Structures

• Address here the SCT region and the replacement of the TRT with silicon strip modules.

• Pursue certain generic or basic R&D to flesh out eventual direction(s).

• The modularity required or adopted will be effected by a number of factors– Experience from present SCT effort– Radius, occupancy, simulations– Material– Assembly logistics, cost, and schedule

• Starting concept is a stave (multi-module) structure as was studied for CDF Run2b

3 Phases + Related Project• Phase 1: (FY05) Explore behavior of ATLAS electronics on a stave,

leverage Run2b experience.– Assemble mock and real staves at LBNL and then BNL

• BNL Strip-pixel project: (FY05) Development of an ATLAS specific single-sided 2D detector.

• Phase 2: (FY05)Test of strip-pixel detector with analog and ATLAS binary readout at BNL.

• Phase 3: (FY06) Development of new ATLAS specific stave with strip-pixel or other appropriate readout.
