Description
Cosmic ray tomography usually focusses on two key approaches: muon transmission and muon scattering tomography. Secondary particles produced from the interaction of air shower particles with the target material have not been fully exploited so far, although they have been proven to carry complementary information directly related to the target material properties. Previous work [1] showed a novel approach utilizing only the information from secondary particles to successfully reconstruct and discriminate a variety of materials in the context of a shipping container scanner with an optimal detector setup and background-free environment.
This work builds on Ref. [1], taking into consideration realistic detector parameters and investigating their impact on material reconstruction and discrimination methods. A possible detector setup is discussed, allowing the reconstruction of muons and secondary particles from different energy regimes. Three key detector parameters, mainly the detection efficiency, the spatial resolution and the spacing between the detector layers, are varied with the aim of validating the approach discussed in Ref. [1] in a more realistic scenario.
