| contents | A combination of scintillator, wavelength shifting (WLS) fiber, and silicon photomultiplier (SiPM) shows an excellent performance in the `$K_{L}$ and $μ$ detector (KLM)' of the Belle II experiment. In this study, we present the R&D efforts for a similar detection technology utilizing a new scintillator and SiPM. This technology can be applied to a muon detector for the proposed CEPC experiment. The R&D encompasses the investigation of the performance of a new 150 cm-long scintillator, the NDL SiPM with a sensitive surface of $\times$ 3 mm, or the Hamamatsu MPPC with a sensitive surface of 1.3 mm $\times$ 1.3 mm. Additionally, it includes the construction of a detector strip and the methods employed to achieve excellent light collection. Cosmic ray tests reveal efficient photon collections by NDL SiPM or MPPC, with efficiencies well above 90% using a threshold of 8 p.e.. The time resolutions for hits at the far end of a scintillator strip are better than 1.7 ns. The observed performance lays the foundation for advancing R&D including prototype modules aiming for reference Technical Design Report of CEPC detector recently. |
