Challenge for Detector Design and Technology
Editors (John Jaros) + Tim Barklow + Henri Videau + Keisuke Fujii Outlines
Jet energy resolution: Required lum. vs resolution.– (WW/ZZ), Br(HWW*), (HHZ), SUSY(WW/ZZ)
Momentum resolution:– Recoil mass of ZH llX , Slepton Mass,
Lum weighted ECM det. from pair and Vertexing at ILC
– Br(Hbb), Br(Hcc,gg), AFB(bb) with vertex charge– Challenges imposed by the ILC beam structure
Beamcal – High rad. Env., reacdout each bunch, need to veto H.E. e
at the smallest possible angle – S(SUSY) vs veto efficiency, electron angle, ..
Others– Ebeam, Pol., High B Solenoid., Muons, required R&D

Sub-Detector Performance
Philosophy Pickup typical results from concept studies in order to show that
detector performance used in the physics chapter is confirmed with some extent by full simulations.
Basics Material budget of detectors
Tracker performacne Momentum resolution:
TPC (GLD, LDC, 4th), SiD Track reconstruction
– TPC: Old Tesla TDR result – SiD: VTX based, ECAL Based + SiD standalone

Comparison of Momentum Resolution
LDC
GLD
GLD vs LDC• Difference in Low Pt region ? Is it by IT matterial ?•High Pt: TPC only resol. Different. Spatial resolution difference ? With VTX/IT Constraint, similar performance.No CosTheta dep. From GLD.
SiD

Calorimeter and PFA Performance
Calorimeter performance for single particle /electron energy resolution & angular resolution Pi+/Kaon_L energy resolution & angular resolution
PFA issues Describe what is PFA Typical PFA algorithm(s) Typical PFA performance at Z pole and higher energy
– Resolution : 90% RMS– SiD result ?– LDC – 30%/sqrt(E) at Z pole, but not good for ttbar, 500GeV– GLD – 30%/sqrt(E) at Z pole, barrel region
+ Not good in endcap region Hope to improve soon+ Still tile geometry. Strip geometry ? + High Energy performance not good.
Hope : good for baseline physics

Time line to prepare the detector chapter
Time line: At Vancouver:
– Propose the outline– Authors are nominated/selected
By End of September– First draft including major part of figures collected.– Some figures will be preliminary
By End of October=ECFA meeting at Valencia– Combine drafts, make a balance, editing, draft open
to society By End of November
– Get feedback from community By end of 2006:
– Shape up and complete DCR
Slower than the initial plan
