AI 中文摘要
已建造ENUBET带仪器的衰变隧道的最终全尺寸原型（称为演示器），并在2022、2023和2024年于CERN东区域设施开展的束流测试期间对其性能进行了测试。我们展示了这种专用纵向采样量热计技术的完全可扩展性，该技术基于铁吸收体、波长位移光纤和硅光电倍增管（SiPM）读出的闪烁体砖。此外，我们使用能量高达5 GeV的带电粒子束，评估了逐通道响应以及电子能量分辨率、线性度和粒子鉴别能力方面的性能。还给出了与该原型的GEANT4模拟预测的比较结果。这些结果满足通过衰变隧道中轻子鉴别进行中微子监测的要求，并验证了ENUBET全模拟。尽管已发现一些局限性，但这些局限性可在未来开发中轻松解决。
英文摘要
A final full-size prototype of the instrumented decay tunnel of ENUBET, referred to as the Demonstrator, was constructed and its performance was tested during the 2022, 2023 and 2024 beam test campaigns at the CERN East Area facility. We demonstrate the full scalability of this specialized longitudinal sampling calorimeter technology, based on iron absorbers and scintillator tiles readout by wavelength-shifting fibers and SiPMs. In addition, we evaluate the channel-by- channel response and the performance in terms of electron energy resolution, linearity, and particle identification capabilities, using charged particle beams with energies up to 5 GeV. A comparison with the predictions of a GEANT4 simulation of the prototype is also presented. The results meet the requirements for neutrino monitoring through lepton identification in the decay tunnel and validate the ENUBET full simulation. Although some limitations have been identified, they can be readily addressed in future developments.
