Universidad de Zaragoza (orcid)0009-0006-7877-2985 Characterization of a radiation detector based on opaque water-based liquid scintillator 2024 Access copy available to the general public Unrestricted We present the characterization of a novel radiation detector based on an opaque water-based liquid scintillator. Opaque scintillators, also known as LiquidO, are made to be highly scattering, such that the scintillation light is effectively confined, and read out through wavelength-shifting fibers. The 1-liter, 32-channel prototype demonstrates the capability for both spectroscopy and topological reconstruction of point-like events. The design, construction, and evaluation of the detector are described, including modeling of the scintillation liquid optical properties and the detector’s response to gamma rays of several energies. A mean position reconstruction error of 4.4 mm for 1.6 MeV-equivalent events and 7.4 mm for 0.8 MeV-equivalent events is demonstrated using a simple reconstruction approach analogous to center-of-mass. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 1.4 2024 INSTRUMENTS & INSTRUMENTATION 57 / 79 = 0.722 2024 Q3 T3 PHYSICS, PARTICLES & FIELDS 21 / 31 = 0.677 2024 Q3 T3 PHYSICS, NUCLEAR 15 / 22 = 0.682 2024 Q3 T3 NUCLEAR SCIENCE & TECHNOLOGY 23 / 41 = 0.561 2024 Q3 T2 0.451 2024 Nuclear and High Energy Physics 2024 Q2 Instrumentation 2024 Q2 2.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Asquith, L.
