We report on the results of the positional-dependent pulse shapediscrimination (PSD) parameter observed within a monolithic CLLB scintillationcrystal. CLLB, a relatively novel inorganic scintillation crystal, is capableof PSD between gamma rays, neutrons, and alpha particles. In this work, weobserved distinguishable differences in the pulse shapes for gamma-ray-inducedevents. The CLLB crystals used for this experiment are 5 cm (diameter) by 10 cm(length). By using monoenergetic 2.614 MeV photons from a set of thoriatedwelding rods and performing collimated scans along the length of the crystal,we found that the centroid of the PSD distribution shifted as a function ofposition. With positional-dependent PSD, one can obtain more accurate knowledgeof the interaction location within a monolithic scintillation crystal. Theseresults could lead to improved angular resolution in imaging systems employingscintillation crystals that exhibit this behavior. Lastly, an understanding ofthe dependence of the PSD as a function of position could give manufacturers abetter understanding of the crystal properties and provide insight to thedistribution of internal contaminants and dopants within the crystal.
