This contribution describes the first results obtained within the iMPACT project, which aims to build a novel proton computed tomography (pCT) scanner for protons of energy up to 230 MeV, as used in hadron therapy. We will
first describe the design of the iMPACT scanner, which is composed by a tracker and a range calorimeter. Results of test-beams, focused on the characterization of the building elements of the prototype of the calorimeter, will be presented and compared with simulations
