Description
Scintillation detectors are often used for gamma spectroscopy given their performance in measuring the energy and timing of gamma radiation. Typical detectors, that make use of photomultiplier tubes cannot provide accurate data regarding the particle interaction position. Such setups exist but their scale and position resolution make them unsuitable for practical applications. The introduction of silicon photomultipliers has transformed these setups into viable alternatives, overcoming the limitations of conventional detectors. In my work I utilize a matrix of silicon photomultipliers and a thin scintillator to construct a detector capable of pinpointing the particles’ interaction locations with high resolution. For this to be accomplished, the elaboration of a reliable testing platform and data processing procedure was necessary in order to test the precision and accuracy of such setups. Precise measurements of particle interaction positions were obtained by raster scanning the detector using a collimated 241Am gamma radiation source. For the data processing, special algorithms to extract the interaction position from data provided by the detector were used.
