In this work, we report and compare the results of gamma-ray spectroscopy measurements performed using a LaBr3:Ce crystal coupled to a photornultiplier tube with modified base and to a Si-avalanche photodiode readout by standard electronics. Energy resolution values have been obtained in the range from 59.5 keV (Am-241) to 1332 keV (Co-60). Good linearity in energy response has been found. Energy resolution values obtained with avalanche photodiode readout are underestimated due to the small active area of the presently available photosensor with respect to crystal dimension.

Abstract
In this work, we report and compare the results of gamma-ray spectroscopy measurements performed using a LaBr3:Ce crystal coupled to a photornultiplier tube with modified base and to a Si-avalanche photodiode readout by standard electronics. Energy resolution values have been obtained in the range from 59.5 keV (Am-241) to 1332 keV (Co-60). Good linearity in energy response has been found. Energy resolution values obtained with avalanche photodiode readout are underestimated due to the small active area of the presently available photosensor with respect to crystal dimension.
