Abstract

Cs2LiYCl6 (CLYC) is a new scintillator suitable for dual gamma-neutron detection. The crystal contains 6Li and 35Cl, thus thermal neutrons are detected through 6Li(n,α)t reaction and fast neutrons through 35Cl(n,p)35S reaction. In this work, a Monte-Carlo model of a 1x1 inch crystal was developed and validated with experimental data as part of a research group interested in possible future applications in safeguards and medical radiation protection at SCK-CEN. Measurements confirmed the good resolution of the CLYC with ~5% at 662 keV. MCNP6 was employed to model the measurements performed with the detector. A least square minimization implemented in a ROOT environment was used to calculate the response function (energy calibration and resolution function) of the detector comparing the measured and the simulated responses.
