A prototype for the instrumented decay tunnel of ENUBET was tested in 2018 at the CERN East Area facility with charged particles up to 5 GeV. This detector is a longitudinal sampling calorimeter with lateral scintillation light readout. The calorimeter was equipped by an additional "$t_0$-layer" for timing and photon discrimination. The performance of this detector in terms of electron energy resolution, linearity, response to muons and hadron showers are presented in this paper and compared with simulation. The $t_0$-layer was studied both in standalone mode using pion charge exchange and in combined mode with the calorimeter to assess the light yield and the 1 mip/2 mip separation capability. We demonstrate that this system fulfills the requirements for neutrino physics applications and discuss performance and additional improvements.

ENUBET 正电子标记器原型:构造和测试光束性能

ENUBET 仪器衰减隧道的原型于 2018 年在欧洲核子研究中心东区设施进行了测试,带电粒子高达 5 GeV。该检测器是具有横向闪烁光读出的纵向采样量热计。热量计配备了额外的“$t_0$-layer”,用于计时和光子辨别。本文介绍了该探测器在电子能量分辨率、线性度、对 μ 子和强子簇射的响应方面的性能,并与模拟进行了比较。在使用 pion 电荷交换的独立模式和与量热计的组合模式下对 $t_0$ 层进行了研究,以评估光输出和 1 mip/2 mip 分离能力。我们证明该系统满足中微子物理应用的要求,并讨论了性能和其他改进。
