A particle radiography device, designed and developed with the aim of achieving real-time data acquisition and large detection areas, is presented. The prototype is composed by a residual range detector and a tracker. The residual range, consisting of a stack of sixty ribbons of 500 micron square BCF12 scintillating fibers (Sci-Fi), has a sensitive area of about 9 × 9 sqcm and a range of 3 cm water equivalent. Each layer is read-out by two wavelength shifter (WLS) fibers and a 8x8 pixels, 3 sqmm, matrix of Hamamatsu MPPC sensor. The Bragg peak shape is calculated real-time by the time over a suitable threshold for each channel. The tracker, based on 500 micron square BCF12 Sci-Fi has a sensitive area of about 9 × 9 sqcm and about 150 micron spatial resolution. For each particle the crossing position of the tracker and the range is acquired in time coincidence real-time. The results of the measurements taken using the prototypes and a 62 MeV proton beam and a comparison with the GEANT4 simulations of the detector are presented. In order to achieve the prefixed objectives and to determine the main choices, accurate GEANT4 simulations and a precise characterization of different types and sizes of scintillating optical fibers, available on the market, have been performed. Test results of the measurements performed with 62 MeV proton beam of CATANA facility at Laboratori Nazionali del Sud are presented.
