A detector for muon tomography: Data acquisition and preliminary results

I describe the general design of the prototype particle detector constructed by the Maya Muon Tomography Group and how it can be used to e ectively \x-ray" building and ground structure in a location of interest using cosmic-ray muons. I give detailed descriptions of the high level data acquisition and tracking systems, which are responsible for reconstructing muon trajectories from raw data. In addition, I present the rst images obtained from the detector. These images show the basic features of several University of Texas buildings in the vicinity of the Engineering Science Building and demonstrate the feasibility of muon tomographic imaging with our detector.
