“…A strip 170 cm long and 17 cm wide, and 1 cm thick, is used in the anti-coincidence detector of the Large Area Telescope, which requires flexible clear fiber cables up to 1.5 m long to deliver generated light to photomultiplier tubes (PMTs) [9]; OPERA TT [10] will be re-used in JUNO for cosmic muon tracking, where its basic module is composed of 64 scintillator strips with the size of 6.86 m long, 10.6 mm thick, 26.3 mm wide, where a wavelength shifting fiber embedded in the middle, and another 40 cm space is required at each end to couple the optical fiber to the PMT. These detectors give us a lot of inspiration for detector design including in [11,12]. In addition, the flexible characteristics of optical fiber can be used for some arrangements in plastic scintillators, so that photons can be collected with small-size sensors to improve the detection efficiency.…”

Muon veto is an important technique of many low background experiments. With the push in improving the sensitivity and statistics, the size of the detector for particle experiments has also been increasing. Therefore, there is a greater demand on the size of the muon veto system to efficiently identify muon events passing through the detector, minimizing the associated dead time of the target detector, and simultaneously fitting in the space requirements. In this paper, two designs of muon veto detectors composed of 200 cm×20 cm×2 cm plastic scintillator strip and a wavelength shifting(WLS) fiber coupled with SiPM, are tested. We use cosmic muons to examine the plastic scintillator along the length by scintillator cubes as probes and therefore measuring photoelectron numbers as a function of position. The design of layout-4 meets the needs of JUNO-TAO and is a compact and cheap candidate.
