Abstract
Abstract
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.
