Study of a cosmic ray detector based on drift tubes

Muon tomography is a promising imaging technique for the inspection of dry storage casks (DSC) for spent nuclear fuel. Recently, it has been proposed to implement drift tube detectors to control the content of DSCs. The main objective of this thesis is the analysis of the radial and longitudinal spatial resolution of a drift tube detector. The muon tomography demonstrator installed at Legnaro National Laboratories, consisting of two CMS chambers, has been used to reconstruct the muon tracks and to provide a trigger system for the drift tube. Furthermore, a simulation of the muon flux has been performed to test the optimal position of CMS superlayers with respect to detectors, obtained by joining several layers of drift tubes of the type described in this study, placed around a CASTOR®-V cask.
