Preliminary research on application of muon energy measurement based on TOF for muon tomography

Cosmic-ray muon tomography based on multiple coulomb scattering is typically applied in detecting high-Z materials. The energy of muon also plays an important role in the distribution of the scattering angles, and the information of muon energy would be useful for the image reconstruction. In this paper, a simulation experiment has been conducted to check the feasibility of TOF method applied in measuring muon energy for muon tomography system. The simulation results have been discussed and some preliminary conclusions have also been drawn.
