  Cesium Yttrium Chloride (CLYC:Ce)

Cesium Yttrium Chloride (CLYC:Ce)

for Dual Neutron & Gamma Radiation Detection

Cesium Yttrium Chloride (Cs2LiYCl6:Ce) is an elpasolite material with excellent dual gamma

and neutron detection efficiency. CLYC crystals that incorporate 95% 6Li permit thermal

 neutron detection, while 7Li enriched CLYC enables fast neutron detection. CLYC has a light

 yield of about 20,000 ph/MeV of gamma energy and 70,000 ph/neutron while energy

 resolution ranges from 4-5%。 The emission of CLYC is comprised of core-valence

 luminescence (CVL), Ce3+ emission, and emission from Ce3+-self-trapped exciton (STE)

 interaction, resulting in three decay components on the order of several ns (CVL), hundreds

 of ns (Ce3+), and several µs (Ce3+-STE). Absence of CVL under neutron excitation allows for

 easy discrimination between the neutron and gamma radiation. An FOM value of 1.85 was

 

achieved using a SiPM.CLYC can be used for a variety of portable detection instruments (e。g。 handhelds as well as

     back-packs). CLYC is currently available in different geometries, with or     without 

 encapsulation. Inquire for more details.
