  8. ▣ R&D Activities: Jet Chamber • 4.6 m Test Jet Chamber (6 axial and 10 stereo super layers) √ measurements of wire tensions and positions √ cosmic ray tests with a candidate gas mixtures √ space charge effect measurement √ basic chamber studies with “baby” chamber √ spatial and momentum resolution √ two track separation √ wire material studies √ full CDC detector simulator based on Geant4

  9. ▣ R&D Activities: Si µ-strip central tracker (with NLC detector parameters) √ Full Simulation Study for detector parameter √ reconstruction efficiency √ momentum resolution √ photon background simulation • - - #hit1 in central • & #VXD hit=5 • - - #hit2 in central • & #VXD hit=5 - - - #hit3 in central - - - #hit=5 in central |cosq|<0.8

  10. ▣ Summary □ Vertex Detector - spatial resolution and distortion of thin wafers measured - innermost layer survive more than 3 years under option “A” - radiation damage effect studied □ Intermediate Tracker - fast and full simulation with 5 layers - Si µ-strip R&D proposal submitted (pending) □ Central Tracker - chamber parameters studied with “baby chamber” - track momentum and two track separation - Si µ-strip R&D started (detail simulation studies carried)
