They share many characteristics with LaBr₃ but provide improved mechanical strength. ##### Key Properties of LBC Scintillation Detectors - **Energy Resolution** — Typically 3% FWHM at 662 keV, offering better performance than the ~4% commonly seen with CeBr₃ detectors. - **Mechanical Durability** — Stronger than standard LaBr₃, reducing risk of cracking or damage in handling or field use. - **Intrinsic Background** — Contains trace La-138 (similar to LaBr₃), producing a low-energy background line around 32 keV; this can be subtracted via background acquisition in most measurement setups. - **Hygroscopic Nature** — Requires encapsulation to protect against moisture absorption. ##### Available Configurations - Encapsulated crystals with entrance window. - Crystals integrally coupled to light sensors (PMT or SiPM). - Complete detector assemblies including light sensor and front-end electronics (preamplifier, shaping, etc.). Crystal sizes range from small pixels suitable for arrays to larger volumes up to 102 mm × 127 mm, supporting single-detector or multi-detector systems. These **high-resolution gamma scintillation detectors** are applied in: - Nuclear safeguards and non-proliferation inspections - Environmental radioactivity monitoring - Homeland security and nuclide identification - Waste characterization and decommissioning - Gamma spectroscopy research requiring clear peak separation For specifications on energy resolution, crystal dimensions, background subtraction methods, or to discuss LBC detector configurations for your gamma spectroscopy application, contact us or complete our brief detector survey form. We can help select the appropriate setup based on your energy range and environmental needs.
