The Cs2LiYCl6 (CLYC) scintillator is proven to be suitable for dual γ-ray/neutron detection owing its distinct response both radiation types. This feature makes this material attractive applications in nuclear security and safeguards. Two 3.8 cm diameter CLYC crystals, one enriched with 95% 6Li, the second depleted of 6Li >99% 7Li, were characterized conventional gamma-ray sources as well (α, n...
