چکیده انگلیسی
A Time of Flight Positron Emission Tomography scanner based on plastic scintillators is being developed at the Jagiellonian University by the J-PET collaboration. The main challenge of the conducted research lies in the elaboration of a method allowing application of plastic scintillators for the detection of low energy gamma quanta. In this paper we report on tests of a single detection module built out from the BC-420 plastic scintillator strip (with dimensions of 5Ã19Ã300Â mm3) read out at two ends by Hamamatsu R5320 photomultipliers. The measurements were performed using collimated beam of annihilation quanta from the 68Ge isotope and applying the Serial Data Analyzer (Lecroy SDA6000A) which enabled sampling of signals with 50Â ps intervals. The time resolution of the prototype module was established to be better than 80Â ps (Ï) for a single level discrimination. The spatial resolution of the determination of the hit position along the strip was determined to be about 0.93Â cm (Ï) for the annihilation quanta. The fractional energy resolution for the energy E deposited by the annihilation quanta via the Compton scattering amounts to Ï(E)/Eâ0.044/E(MeV) and corresponds to the Ï(E)/E of 7.5% at the Compton edge.
