4. Challenge for Detector Design and Technology • Editors (John Jaros) + Tim Barklow + Henri Videau + Keisuke Fujii • Outlines • Jet energy resolution: Required lum. vs resolution. • s(nnWW/ZZ), Br(HWW*), s(HHZ), SUSY(WW/ZZ) • Momentum resolution: • Recoil mass of ZH llX , Slepton Mass, Lum weighted ECM det. from m pair and mmg • Vertexing at ILC • Br(Hbb), Br(Hcc,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 Gakujyutsu Sousei Monthly Meeting

5. Subsystem designs and technologies • Prepared by R&D panel members and experts • Authors assigned • Beam CAL : Ray Frey • Vertex detector : C. Damerell • Tracker – TPC : Dean Carlen - Silicon: • Calorimeter: Wolfgang • Solenoid : Akira Yamamoto • DAQ: Ecklund • Correcting outlines on each topics Gakujyutsu Sousei Monthly Meeting

6. 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 Gakujyutsu Sousei Monthly Meeting

7. Comparison of Momentum Resolution GLD LDC • 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 Gakujyutsu Sousei Monthly Meeting

8. Track Reconstruction SiD LDC ( Tesla TDR ) SiD promissed better pictures By the end of Oct. Gakujyutsu Sousei Monthly Meeting

9. Calorimeter and PFA Performance • Calorimeter performance for single particle • g/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 Gakujyutsu Sousei Monthly Meeting

10. Typical PFA result GLD PFA Gakujyutsu Sousei Monthly Meeting

11. PFA – cont. • Particle ID's in jets (PFA) • Good PFA includes efficient and pure ID of g, e, m • Typical particle ID efficiency/purity shall (should ) be described. • What studies should be described and How ? Gakujyutsu Sousei Monthly Meeting

12. Vertexing Performance • Impact parameter resolution: 2D or 3D • SiD, GLD, LDC (wil) have simular performance • Efficiency and purity of b/c tagging and vertex charge ID. • Mostly based on fast simulation. • How to describe ? Gakujyutsu Sousei Monthly Meeting

13. + Impact Parameter resolution I LDC ~1.5 mm at 100 GeV ~13 mm at 1 GeV SiD promissed similar plot by the end of Oct. Need a plot of cosq dependance. Gakujyutsu Sousei Monthly Meeting

14. Muon ID • Pt threshould to be identified by muon detector • How highly-segmented calorimeter is effective to identify low momentum muon particles ? GLD case Calorimeter based muon ID will be useful Gakujyutsu Sousei Monthly Meeting

15. Beam Calorimeter • Describe typical electron tagging efficiency • Dependance on • Beam parameters • Crossing anlge Gakujyutsu Sousei Monthly Meeting

16. 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 Gakujyutsu Sousei Monthly Meeting
