Three-dimensional finely grained plastic scintillator detectors offer advantages in high-precision tracking, excellent calorimetry, and sub-nanosecond time resolution, but face challenges in production time and assembly. This manuscript introduces a novel design for efficient and cost-effective detector construction. This work could be particularly relevant for next-generation long-baseline neutrino-oscillation experiments.
Three-dimensional finely grained plastic scintillator detectors bring many advantages in particle detectors, allowing a massive active target which enables a high-precision tracking of interaction products, excellent calorimetry and a sub-nanosecond time resolution. Whilst such detectors can be scaled up to several-tonnes, as required by future neutrino experiments, a relatively long production time, where each single plastic-scintillator element is independently manufactured and machined, together with potential challenges in the assembly, complicates their realisation. In this manuscript we propose a novel design for 3D granular scintillator detectors where O(1 cm(3)) cubes are efficiently glued in a single block of scintillator after being produced via cast polymerization, which can enable rapid and cost-efficient detector construction. This work could become particularly relevant for the detectors of the next-generation long-baseline neutrino-oscillation experiments, such as DUNE, Hyper-Kamiokande and ESSnuSB.
