Lanthanum Bromide [LaBr3(Ce)] scintillation material has been the reference for excellent energy resolution combined with fast emission and good linearity.
Lanthanum Bromide scintillation crystals are available integrated designs. Light sensor selection and integration, as well as the use of specific electronics, are key to optimizing performance.
Lanthanum Bromide is hygroscopic and must be hermetically packaged with a light-sensing device [such as a photomultiplier tube (PMT) or silicon photomultiplier (SiPM)]. The proper packaging and integration of scintillation crystals is a science combining advanced design and engineering skills with proven assembly techniques and materials to produce stable, high-resolution radiation detectors.
Saint-Gobain Crystals offers a variety of detector designs to fulfill most radiation counting applications: a packaged scintillator, a scintillator integrated. It can also be packaged for high temperature, rugged environment for oil well logging application.
