3 QuickSim overview Purpose: simulate detector effects for physics study Components:  VTX, IT, TPC, CAL Model for tracker  circular trajectory  parabolic trajectory  With multiple scattering, without energy loss  Equally spacing sampling Model for Calorimeter  EM signal by e/ , HD signal by hadron, muon no signal  Segmented calorimeter. Lateral spreads are generated by an analytic form. Detector configuration is determined by input ASCII file.

4 QucikSim Parameters Detector performance is determined by input parameters.  Parameter set gld_v3.comgld_v4.com Energy resolution of each cell and cell sizes are adjusted Configuration files are at

5 QuickSim Tracker performance Momentum resolution similar to the Jupiter/Satellites result IP resolution at 1 GeV is about factor 2 worse than the Jupiter/Satellites result
