Description
The natural flux of cosmic-ray muons impinges upon the Earth’s surface allows us to study the interior composition, density and obtain 3D-reconstructions of geological and human-made structures using muon detectors.
In this contribution, we describe the state-of-the-art muon tracking system developed by the company GScan in collaboration with our research partners. The detector system utilises orthogonally arranged scintillating fibres for detection and Silicon Photomultipliers for readout. The prototype has achieved an excellent spatial resolution of 120 μm and 1 mrad angular resolution in the track reconstruction, as well as demonstrated the ability to differentiate objects composed of low-Z materials. Furthermore, our detector system showed an excellent agreement between the Geant4 modelled and measured data.
The developed detector system has opened up new opportunities for commercial applications in the fields of security, customs and non-destructive testing (NDT), to name a few. This new technology offers numerous advantages over traditional inspection methods, including its ability to penetrate dense materials without harmful radiation whilst providing information about both the physical and chemical structure.
In this talk, we will discuss the current status of the GScan detector development, automated production and its applications towards security, customs and NDT scanner systems. In addition, we will present the results from the first tomographic measurements: spatial resolution, material classification power, etc.
