## 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.
