Abstract

The capabilities of ⁷Li-enriched Cs₂ ⁷LiYCl₆ (C⁷LYC) scintillation detectors for fast neutron spectroscopy are explored in benchmark experiments that exploit its excellent pulse-shape discrimination between neutrons and γ rays, and its unprecedented ≈10% energy resolution for fast neutrons in the few MeV range, obtained through the ³⁵Cl(n,p) reaction. Energy- and angle-resolved elastic and inelastic neutron scattering cross-section measurements of ⁵⁶Fe(n,n’) were performed at Los Alamos National Laboratory with a pulsed white neutron source and an array of 1^″×1^″ C⁷LYC crystals. The results convincingly establish the utility of this dual n/γ scintillator for fast neutron spectroscopy. Intrinsic efficiency measurements of both 1^″×1^″ and the first ever 3^″×3^″ C⁷LYC crystal have been initiated, using mono-energetic fast neutron beams at UMass Lowell generated via the ⁷Li(p,n) reaction. The spectroscopic capabilities and potential of C⁷LYC are discussed in the context of developing this emerging scintillator for targeted science applications.
