Abstract: CeBr<subscript>3</subscript> crystals have been studied to assess their utility as potential gamma ray spectrometers for future ESA planetary missions. Pulse height spectra, scintillation time profiles, X-ray excited emission spectra, and photoluminescence spectra have been recorded as a function of temperature between 78 and 600 K. In addition, the influence of exposing CeBr<subscript>3</subscript> to various doses of gamma rays from a strong <superscript>60</superscript>Co source on its scintillation performance has been investigated.
