Why a SiD Design Study Now?
• Timing. Things are happening. WWS wants detector costs,
concepts, and R&D requirements in 2005. 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
Goals for SiD Design Study
Develop an integrated detector design wellmatched 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.
