Detector characterization and spectroscopy with C$^{\mathrm{7}}$LYC n/gamma scintillators

POSTER

Abstract

Fast-neutron detection and spectroscopy is important for both basic and applied Nuclear Science. Inorganic $^{\mathrm{7}}$Li-enriched Cs$_{\mathrm{2}}^{\mathrm{7}}$LiYCl$_{\mathrm{6}}$:Ce (C$^{\mathrm{7}}$LYC) scintillation detectors are an emerging technology that provide unprecedented ($\approx $10{\%}) energy resolution for fast neutrons in the few MeV range, obtained through the $^{\mathrm{35}}$Cl(n,p) reaction. Additionally, the scintillators are sensitive to gamma rays, having an efficiency and energy resolution similar to NaI. Superior pulse-shape discrimination properties enable extremely clean identification of neutron and gamma events. Measurements using both sources and nuclear reactions generated with a 5.5-MV Van de Graaff accelerator have been carried out at UML to further explore their potential, including scattering experiments as test of their full spectroscopic potential. An overview of C$^{\mathrm{7}}$LYC digital pulse-shape analysis techniques as well as timing and spectroscopy measurements will be presented.
