Discussion/Interest? All
Next Steps Harry

3. Why a SiD Design Study Now?
Timing. Things are happening. WWS wants detector costs, concepts, and R&D requirements in Time to get moving!
Homework before the Exam. More of the world-wide HEP community needs to engage in LC detector design and R&D now to be ready for productive participation in upcoming LC Detector Collaborations.
LC Physics, Round 2. Forget your favorite fastsim. What will the real physics look like, with real backgrounds (physics and machine), in a real detector (with noise, segmentation, and realistic response)? How does physics performance depend on detector design, performance, and cost?
Integrated Detector Concepts define/justify detector R&D

4. Goals for SiD Design Study
Develop an integrated detector design well-matched to LC physics at .5 and 1 TeV, starting from the SiD Detector Concept.
Generate a realistic picture of detectors, supports, readout, and services for each subdetector technology.
Optimize overall detector physics performance for benchmark reactions, constrained by rational cost.
Define the R&D needed to prove the design concept.
Estimate detector costs in time for the Machine CDR.
Write a CDR describing the design and its expected physics performance. Refine costs estimates in time for the Machine TDR.

5. SiD is a Starting Point
Next Evaluate the performance Fill in the details Refine the concepts …Iterate

6. Evaluate the Performance e.g. Tracking
Revisit Backgrounds Tim Barklow SLAC ALCPG .25   hads
Occupancy studies Toshi Abe Victoria ALCPG < 1% for 200 bunches!
Pattern Recognition Studies Erich von Toerne, Nick Sinev, Steve Wagner Victoria ALCPG VXD  Barrel  Ecal  Forward ???

7. Fill in the Details e.g. Fermilab and Brown U

8. Refine the Concept e.g. Tracking
Endcaps on Vxd?
Disks or Endcaps? Fermilab/Brown U

9. …Iterate Forward pattern recognition.
Must we track K shorts and lambdas?
Revisit Momentum/Angular Resolution Requirements
Tracking Efficiency in Jet core
Need more layers, A/S for pat rec?
