             abstract = "The Mario Schenberg gravitational wave antenna is a spherical 
                         cryogenic resonant mass detector located at IFUSP, S{\~a}o Paulo. 
                         It is well known that cosmic rays interact with cryogenic resonant 
                         mass detectors generating acoustic signals. Depending on the 
                         shower energy, they could provide a substantial background noise 
                         which should be vetoed to reduce the false alarm rate. For this 
                         purpose, in December 2011, we have installed a cosmic ray veto 
                         system which is, since then, acquiring data. The cosmic ray veto 
                         system is composed of three particle detectors containing each one 
                         a scintillator, a photomultiplier and a tension divider. As the 
                         shower number of particles is used to define a threshold for the 
                         veto, it is important that the cosmic ray veto provides a linear 
                         response to high-energy cosmic ray events. The veto setup response 
                         was optimized and allows measurements up to 23,000 equivalent muon 
                         charge particles per square meter. We present here the 
                         experimental setup, its calibration and performance. Finally, to 
                         confirm the linearity of the data acquisition we show the measured 
                         particle multiplicity. © 2014 Elsevier B.V.",
