摘要
In this paper,the design,construction,simulation,and performance of a position-sensitive plastic scintillator detector are presented.The readout of the detector uses wavelength-shifting fibers coupled with multi-anode photomultipliers(PMTs) for the x-and y-dimensions.After calibrating the multi-anode PMTs,a two-dimensional projection image of the square scintillator telescope hit by cosmic muons is demonstrated.By performing a cosmic test with the Micromegas telescope,the position resolution of the detector was determined to reach approximately8.6 mm,which is close to the value obtained in physical simulation.
