Measurement of the charge ratio of atmospheric muons with the CMS detector
There is increasing interest in the use of cosmic ray muons for tomographic study of large structures, both natural and engineered. This allows non-invasive characterisation of systems without the radiation problems produced by X-Rays and can be used for structures too large for X-Rays to penetrate. Examples include the detection of radioactive contraband dx.doi.org/10.1016/j.nima.2011.01.163; and investigating geological structures for carbon dioxide sequestration dx.doi.org/10.1016/j.ijggc.2012.07.023. In order to plan and interpret such measurements a precise knowledge of the cosmic ray muon flux is required and this paper presents the most precise measurements to date.
