摘 要：Purpose To study the cosmic ray muon tomographic imaging of high-Z material with Micromegas-based tracking *** A high-spatial-resolution tracking system was set up with the micro-mesh gaseous structure(Micromegas)detec-tors in order to study the muon tomographic imaging *** layers of 90 mm×90 mm one-dimensional readout Micromegas were used to construct a tracking *** and conclusion The imaging test using some metallic bars was performed with cosmic ray muons.A two-dimensional imaging of the test object was presented with a newly proposed ratio *** result of this work shows that the ratio algorithm is well performed.
