ABSTRACT:
A method and system for high Z material revealing using muon detection technique is presented. The system measures muons' coordinates, velocities, incidence angles and leaving angles. Two series of detectors: one above and one below the interrogated volume are used. A muon trajectory deviation from an expected trajectory is used for the decision making on the presence of high Z material inside the volume. The muon velocity is measured using either a ring Cerenkov counter, a transition radiation detector or/and a threshold Cerenkov counter. The expected trajectory is calculated basing on known particle velocity.
