【Abstract】 We have developed a large area two-dimensional high position resolution MRPC for muon tomography. The sensitive area of the module is 1 072 mm × 1 072 mm,through a cosmic-ray experiment,the performance of MRPC module is carefully observed and each channel is calibrated. Through an X ray experiment with a narrow slit,the position resolution is studied. The results show that the efficiency is higher than 98%and the spatial resolution can reach 272 μm.更多还原
