A study of several methods to obtain simultaneous measurements of deposited energy and interac-
tion position in monolithic $πΆππ΅π_3$ and $πΏππ΅π_3$ scintillator crystals using a $12\times12$ matrix of $3ππ^2$
silicon photomultipliers was performed by simulation and experiment. A multistep method for
analysis and reconstruction of the data is being implemented. Two data acquisition and analysis
systems - from commercially available modules and an in-house design - are being built to validate
the simulation results and are currently undergoing calibration and testing. The tested detector
system can perform spectroscopy with energy resolution reaching the specification limits of the
scintillator crystals. Depending on the chosen sequence of methods, spatial resolution of 0.65mm
with π = 0.88ππ was achieved after applying the developed event classification and separation
algorithms.
