CLLB [Cs2LiLaBr6(Ce)] is a gamma-neutron scintillation detector that is well suited for many different classes of handheld instruments. Using Pulse Shape Discrimination electronics for Neutron Detection, customers can eliminate the need for an additional set of electronics and 3He detector. With dual gamma/neutron detection and an energy resolution of 4%, CLLB scintillator offers a dramatic change in what is capable in a handheld instrument.
In the past, you needed both an 3He and NaI(Tl) detector to detect gamma and neutron. CLLB is now your compact dual gamma neutron detector solution.
We have been manufacturing CLLB detectors since 2017.

CLLB is hygroscopic and must be hermetically sealed. Cs2LiLaBr6:Ce (CLLB), will always be packaged with a light sensor to maintain the integrity of this hermeticity.
CLLB integrated with a silicon photomultiplier (SiPM) light sensor is under development.
