Version

1.0

The ERBeamDetTrackFinder reconsructs the ion coordinate and momentum direction on the target by means of the digitization output data and ERBeamDetSetup class. It is assumed that we have events with a multiplicity more than one after the digitization stage in each array of wires. In this way, we can calculate an arithmetic average for each cordinate in MWPC stations where all activated wires are neigbours between each other. Through number of wires we get coordinates ( \(X_1, Y_1, X_2, Y_2\)) for each wire by means of global geo manager in ERBeamDetSetup. After that calculate arithmetic averages ( \(<X_1>, <Y_1>, <X_2>, <Y_2>\)) . Ion track approximated by straight line passing through ( \(<X_1>,<Y_1>\)) and ( \(<X_2>, <Y_2>\)) points.
