Description

Muon scattering tomography (MST) using cosmic ray muons of strong penetrating power as probes, is a non-destructive technique explored recently to image dense objects, such as nuclear materials. In this work, a toy Monte Carlo tool is developed to simulate multiple scattering process of muons and spatial resolution of tracking detectors in MST system efficiently. The trackers of the MST system are to be built with plastic scintillating fibers, of which the track angular resolution is obtained from Kalman Filter algorithm. The well-known point of closest approach (PoCA) is applied to evaluate imaging performance of the MST system for different materials. This fast full-chain simulation tool can contribute to explore the influence of detector spatial resolution and layout on imaging performance. To further improve MST identification ability on dense materials, a Cherenkov detector will be introduced to measure muon momentum in the near future.
