3 Introduction. New Spectroscopy Detector - The tool uses a large cerium-doped lanthanum bromide (LaBr 3:Ce) gamma ray detector (Van Loef et al., ; Saint Gobain Crystals, ; Stoller et al., ), which is coupled to a state-of-the-art high-temperature photomultiplier.

LaBr 3:Ce is a very fast scintillator. Gamma spectroscopy systems are designed and adjusted to produce symmetrical peaks of the best possible resolution. The peak shape is usually a Gaussian distribution. In most spectra the horizontal position of the peak is determined by the gamma ray's energy, and the area of the peak is determined by the intensity of the gamma ray and the efficiency of the detector.
