Description
Summary:Radiation Monitoring Devices (RMD) has developed a composite detector technology for multi-mode detection, based on incorporation of the inorganic scintillation material into a pulse shape discrimination (PSD) - capable plastic scintillator, mainly for handheld and backpack applications. The inorganic component is a dual-mode scintillator such as CLYC, CLLBC, or TLYC, capable of detecting gamma-rays and thermal neutrons. The plastic scintillator serves as an optical light guide, and provides gamma and fast neutron detection along with PSD among all the signatures. The advantage of this technology is the multi-mode detection within a single element at a lower cost compared to high quality large single crystals of inorganic scintillators for building highly efficient, large volume detectors. The technology is scalable since composite detector with multiple elements of inorganic scintillator behaves as a large volume single crystal, and the size is not limited by the crystal growth yield issues.
