AI 中文摘要
三维细粒度塑料闪烁体探测器广泛用于需要粒子径迹、鉴别、量热和亚纳秒时间信息的高能物理实验。此外，塑料闪烁体的低成本原则上使得多吨级探测器的可扩展性成为可能。为了规避数百万个微小独立闪烁体体素生产时间长和组装困难的问题，开发并验证了一种新技术，该技术通过机械加工精度将数千个$9 \ imes 9 \ imes 9$ mm$^3$塑料闪烁体立方体粘合在单个大型单片层中，同时确保有效的光学隔离。在这项工作中，我们证明了该技术可以可靠地扩展到$48 \ imes 48$个光学隔离闪烁体立方体的单片层，这是未来吨级探测器所需的尺寸，满足未来中微子探测器和采样量热器的要求。
英文摘要
Three-dimensional fine-grained plastic scintillator detectors are extensively used in high-energy physics experiments where particle tracking, identification, calorimetry and sub-nanosecond timing information are required. Moreover, the low cost of plastic scintillator makes, in principle, the scalability to multi-tonne detectors possible. In order to circumvent the difficulties related to the long production time and the challenging assembly of millions of tiny independent scintillating voxels, a new technology consisting of gluing a few thousand $9 \times 9 \times 9$ mm$^3$ plastic scintillator cubes in a single large monolithic layer with machining precision, while ensuring an efficient optical separation, was developed and demonstrated. In this work we demonstrate that such technology can be reliably extended to a monolithic layer of $48 \times 48$ optically-isolated scintillating cubes, the size required for future ton-scale detectors, fulfilling the requirements of future neutrino detectors and sampling calorimeters.
