Real-time Detectors for Muography

Different types of detectors can be used for muon radiography. Common to all detectors is the ability to track the direction of the incoming muon. Emulsion detectors have very high resolution and no need for electric power, but cannot give real-time information and cannot be used in all environmental conditions. Detectors with electronic readout have generally lower resolution but are more flexible, can be operated in real-time, and can also measure the time of the muon hitting the detector with resolutions as low as few hundred ps in specific setups. Special geometries and assemblies have been used for specific applications, where the size, weight, or shape of the detector are heavily constrained.
