Research on rapid imaging with cosmic ray muon scattering tomography

Abstract

Cosmic ray muons tomography is a non-destructive imaging technique that uses the natural radiation of cosmic ray muons to create tomographic images of objects. This article presents a novel imaging algorithm that effectively utilizes experimental measurement data to achieve rapid and clear imaging of cosmic ray muons. A clear image can be obtained with only 20 min of measurement time and approximately 200 effective muons. However, the current detection flux is only about 0.044 cm - 2 min - 1 , which is significantly lower than the natural cosmic ray flux of about 1 cm - 2 min - 1 .
