Muography (or muon radiography) is a technique that exploits the penetration capability of muons, elementary particles similar to electrons but with mass about 200 times larger. High energy muons are naturally produced in interactions cosmic rays Earth atmosphere. The measurement their absorption matter allows imaging inner structure large bodies. technological developments detection have opened way its application various fields, such as archaeology, studies geological structures, civil...
A sample of 3984 candidates the K+→π+γγ decay, with an estimated background 291±14 events, was collected by NA62 experiment at CERN during 2017–2018.

Abstract Muon radiography is a methodology which enables measuring the mass distribution within large objects. It exploits abundant flux of cosmic muons and uses detectors with different technologies depending on application. As sensitive surface geometric acceptance are two fundamental parameters for increasing collection muons, optimization very significant.
