  1. Brick Finding Package – Status Report A. Chukanov, S. Dmitrievsky, Yu. Gornushkin Joint Institute for Nuclear Research, Dubna LNGS 11th October, 2006

  2. Outline • Package description • Results • Graphical User Interface • Roadmap • Conclusion

  3. Program Algorithm

  4. Cleaning Event Cellular Automation

  5. Reconstruction muon track direction Hough Transform Kalman Filter(from OpRec package) Tracing Method

  6. Reconstruction Hadron Jet direction Reweighting hits method

  7. Define wall with interaction Neural Network

  8. Find Brick Define most probable brick

  9. Results (nmCC events) “1 of 3” Full detector Wall reconstruction efficiency: 1 wall 0.94 0.85 Brick finding efficiency 1 brick 0.71 0.70 2 bricks 0.87 0.85 3 bricks 0.91 0.92

  10. GUI - Event Viewer

  11. Show hits before and after selection Drawing directions of Muon track And/Or Hadron Jet Show particles or deposited energy Open Data files and Save Picture Execute event Zoom buttons Navigation buttons Muon track reconstruction algorithm Interactions type Brick finding options Program Development Button 

  12. Development Online Event Viewer develop the online data conversion to OPERA Root files Map of inserted bricks BMS people Other BF algorithms can be added to our program

  13. Conclusion • Developed BF program (91% efficiency) • Event Viewer is ready for online analysis • We are ready to put the BF package to OPERA CVS repository • We can implement all your suggestions
