Abstract:
Scintillation detectors are often used for gamma spectroscopy given their per-
formance 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 scin-
tillator 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.
