Abstract :
We present a preliminary study on proton calorimetry for pCT (proton computed tomography) system. In a pCT scanner there are a tracking system for proton-path reconstruction and a calorimeter for measurement of residual proton energy. We set up a prototype system using a silicon tracker and a scintillator crystal . In particular, we show the measurements obtained with YAG:Ce scintillator crystal and therapeutic proton beams.
