  1. Muon track direction reconstruction Chukanov Artem for the Dubna group Napoli, 14 December 2007 Electronic Detectors WG Meeting

  2. Reconstruction strategy 1) Preliminary muon track reconstruction OpRec, Hough Transform, Tracing method 2) Muon track digits selection 3) Fitting procedure Procedure was optimized for the higher BF efficiency

  3. Walls selection Select digits from the first 12 walls 12 walls 12 walls

  4. Digits selection Get digits closed to the muon track. Hits density should be small. Rejected planes

  5. Results Distances from primary vertex to muon track Pure Kalman Filter After fitting

  6. Instead of summary • Procedure reject 33% of reconstructed muon tracks • Coordinate resolution: ~2 cm mean ~0.7 cm at peak • Some parameters can be tuned according to muon momentum • This method show better results for MC • Comparison with Data in progress
