本文描述了一个闪烁光纤(SciFi)光束反射镜的设计、仿真和原型,该反射镜能够在低动量的介子、电子和介子混合光束中实现实时粒子识别、动量和位置测定以及通量计数,用于瑞士保罗·谢勒研究所(PSI)的介子-质子散射实验(MUSE)。讨论了实验要求和概念设计,包括用于抑制相邻光纤串扰的混合方案。对不同类型的纤维进行了比较。SciFis 1个平面的定时分辨率为0.40±0.05 ns, 2个重合平面的定时分辨率为0.27±0.03 ns。当至少需要两架飞机开火时,探测效率为98%。
This paper describes the design, simulation, and prototyping of a scintillating-fiber (SciFi) beam hodoscope that enables real-time particle identification, momentum and position determination, and flux counting in a low-momentum mixed beam of pions, electrons and muons for the MUon-proton Scattering Experiment (MUSE) at the Paul Scherrer Institute (PSI), Switzerland. The experimental demands and conceptual design are discussed, including the mixing scheme used to suppress cross-talk between adjacent fibers. A comparison between different types of fibers is given. The timing resolution for 1 plane of SciFis is 0.40±0.05 ns, and for 2 fiber planes in coincidence, it is 0.27±0.03 ns. The detection efficiency when at least two planes are required to fire is 98%.
