Outline Package description Results Graphical User Interface Roadmap Conclusion
Program Algorithm
Cleaning Event Cellular Automation
Reconstruction muon track direction Hough Transform Kalman Filter (from OpRec package) Tracing Method
Reconstruction Hadron Jet direction Reweighting hits method
Define wall with interaction Neural Network
Find Brick Define most probable brick
Results ( CC events) “1 of 3” Full detector Wall reconstruction efficiency: 1 wall Brick finding efficiency 1 brick bricks bricks
GUI - Event Viewer
Execute event Zoom buttons Navigation buttons Open Data files and Save Picture Show hits before and after selection Drawing directions of Muon track And/Or Hadron Jet Show particles or deposited energy Muon track reconstruction algorithm Interactions type Brick finding options Program Development Button
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
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
