Pulse-shape analysis of CLYC for thermal neutrons, fast neutrons, and gamma-rays

Scintillation properties of semiconducting 6LiInSe2 crystals to ionizing radiation

“…3. The fast timing response permitted by the primary decay component of 317 1 ns and secondary component of 14379 ns generates the opportunity for rapid time tagging of neutron events, compared to approximately 400 ns for Cs 2 6 LiYCl 6 [28].…”

Fast neutron response of 6Li-depleted CLYC detectors up to 20MeV

“…In previous work [12,24] that compared the scintillation decay profiles of fast neutron versus thermal neutron induced events in standard CLYC crystals, there was found to be a slight difference in one of the slower components of light output in each case. In Ref.…”

“…In Ref. [12], one of the components of light output, which was tentatively attributed to binary V k -electron diffusion, was found to be 1.42 μs for thermal neutrons and 1.17 μs for fast neutrons. The rise time for thermal neutron induced pulses was also found to be 7 ns slower than for fast neutrons.…”

“…While thermal neutron detection through the 6 Li(n,α) reaction has been the primary focus of study for CLYC [6][7][8], its application in fast neutron detection and spectroscopy has only recently been investigated [9][10][11][12]. Fast neutron detection is based on the 35 Cl(n, p) 35 S reaction.…”

First γ-Decay Studies with CARIBU Low-Energy Exotic Beams

“…CLYC detectors have shown promise as thermal neutron detectors due to their pulse-shape discrimination for neutrons and γ rays, and their high energy resolution. By depleting the 6 Li content of each CLYC crystal, thereby suppressing the thermal and epi-thermal neutron response, they have also shown excellent promise as fast-neutron spectrometers with energy resolution <10% [6].…”
