Performance tests of a LaBr3:Ce detector coupled to a SiPM array and the GET electronics for γ-ray spectroscopy in a strong magnetic field

Measurements have been performed with scintillation crystals of LaBr3:Ce coupled to an array of Silicon Photomultipliers (SiPMs) in a 3 T magnetic field. The SiPMs were read out by digital data acquisition systems, including the GET electronics system. Inside of the B-field, energy resolution values of 3.82% FWHM at 661.7 keV are reported for a 1.5$\protect \relax \special {t4ht=′}\protect \relax \special {t4ht=′}$ cubic LaBr3:Ce crystal coupled to a 6 × 6 array of 6 × 6 mm2 SiPMs. No measurable degradation in energy resolution due to the presence of the strong magnetic field was observed.
