6. 27 September, 2006 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, 4 th ), SiD  Track reconstruction – TPC: Old Tesla TDR result – SiD: VTX based, ECAL Based + SiD standalone

7. 27 September, 2006 Gakujyutsu Sousei Monthly Meeting 7 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
