An extensive air shower trigger station for the Muon Portal detector

The Muon Portal project (〈http://muoni.oact.inaf.it:8080/〉 [1]; Riggi et al., 2013 [2], [5], [7]; Lo Presti et al., 2012 [3]; La Rocca et al., 2014 [4]; Bandieramonte et al., 2013 [6]; Pugliatti et al., 2014 [8]) aims at the construction of a large area detector to reconstruct cosmic muon tracks above and below a container, to search for hidden high-Z materials inside its volume by the muon tomography technique. Due to its sensitive area (about...
