  2. General Overview 1 Detector: Data/Simulation Raw Data Hits (Digis) Geometry DB 1750 Physicists 150 Institutes 32 Countries Laser reconstruction (LaserBeam Model) Once per Run? Alignment Procedure With Laser System (LinLeastSquare!?) Alignment DB (100 mm) Frank Raupach

  3. General Overview 2 Pattern recognition 1. track reconstruction Autoalignment mechanism offline Alignment procedures with tracks (+ laser) (Methods under study) Alignment DB (30 mm) Link to muon system Final track reconstruction Rather complicated: O(20000 Si wafers) Correlations B-field … Reconstructed event to DB Frank Raupach

  4. Key Elements to achieve the Goals 1 Start: CMSIM + ORCA digis in DB Geometry without errors First: MisAlignment procedure in ORCA Alignments tools for ORCA - Deviations on different scales (Helge Voss,…) - LaserBeams … Misaligned digis Here we are able to analyse the influence of wrong position assignment Reconstruction with stiff tracks Reconstruction of laser beams Frank Raupach

  5. Key Elements to achieve the Goals 2 Fast Alignment Procedure e.g. fitting global and local parameters simultaneously Problem of correlated errors Alignment Procedure with tracks + laser Alignment DB Near future Technical meeting On Alignment tools middle of may Physics Analysis with best aligned tracks and vertices e.g. H -> bb, t t, …..
