摘要
介绍了一种应用于缪子成像系统的新型二维高位置分辨探测器,MRPC探测器的有效面积为1 072 mm×1 072 mm,先后对探测器在宇宙线和X射线下测试其性能,结果表明探测效率高于98%,位置分辨好于272μm。
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.
