Muon detectors, systems and methods
A muon detector system capable of determining muon direction and flight trajectory or path is disclosed. The muon detector system includes scintillators for determining muon direction, and an array of muon detectors arranged in orthogonal layers for determining flight trajectory. The system can be used for tomographic and telescopic mode imaging, and may be used for imaging concealed and/or subterranean objects.
1. A imaging method, comprising:
arranging a muon detector comprising a trajectory determination system and a scintillator assembly capable of determining muon direction and trajectory with an object such that muons passing through or around the object are detected by the detector; and
creating an image of the object from detected muons;
wherein the muon detector is placed above the object to detect upward traveling muons;
wherein no component of the muon detector is placed below the object; and
wherein upward is defined as in a direction towards earth's surface and below is in a
direction away from the earth's surface.
2. The imaging method of claim 1 , wherein the object is concealed from the detector.
3. The imaging method of claim 1 , wherein the object is located below ground.
4. The imaging method of claim 1 , further comprising determining the density of the object.
