摘　　要：北京谱仪亮度监测器的探测器在日本KEK进行了束流测试和刻度.在0.25GeV/c到4GeV/C动量范围内,测量了量能器的性能.在电子为1.5GeV/c时,量能器的能量分辨为13％.时间分辨为660ps.定义计数器和辅助计数器的性能也作了测量,半高宽能量分辨率为30—40％,时间分辨为～300ps.实验结果表明探测器的性能可以适用于北京谱仪亮度监测器.The test and calibration of the detectors of the BES luminosity monitor were performed at KEK Japan. In the momentum region from 0.25 GeV/r to 4.0 GeV/c, the properties of the shower counter, such as energy resolution, energy linearity, homogeneity and time resolution were measured. The energy resolution of the shower counter Ox is approximately 13% at 1.5 GeV/c. The time resolution is 660 ps. The performance of the defining counter and the complementary counter was also measured, and the energy resolution was 30—40%, the time resolution was about 300 ps. The experimental results show that the properties of all these detectors are satisfactory for the BES luminosity monitor.
