摘　　要：风云三号E星搭载的中能质子探测器实现了风云三号系列卫星首次对辐射带中能质子进行多方向的测量。中能质子探测器实现了对九个方向的测量能量范围为0.03~5 MeV的中能质子能谱的测量。为确定中能质子探测器的实际性能,在仪器交付前,利用中国科学院国家空间科学中心的中高能电子加速器,对中能质子探测器的能量分辨率,相对响应效率曲线、不同方向探头测量一致性以及抗电子污染能力进行了标定。文中介绍了仪器的标定场所、标定内容,并对标定的结果做了分析。其结果显示,仪器的能量分辨率为6.50%@310 keV,各测量一致性偏差优于1.51%,电子在仪器内产生污染计数的概率低于1%。该结果为中能质子探测器在轨运行时数据的分析处理提供了重要的参考依据。FY-3E is the first satellite among the FY-3 series that has observed protons with medium energy in multiple directions.The medium energy proton detector can measure the energy spectrum of protons with the energy range of 0.03~5 MeV in nine directions.In order to determine the actual performance of the medium energy proton detector,before the instrument delivered,the energy resolution,relative response efficiency curve,measurement consistency of probes in different directions,and anti-electron pollution ability of the medium energy proton detector were calibrated using the medium and highenergy electron accelerator of the National Space Science Center of the Chinese Academy of Sciences.This paper introduces the calibration site and contents of the instrument,and analyzes the calibration results.The results show that the energy resolution of the instrument is 6.50%@310 keV,the consistency deviation of each measurement is better than 1.51%,and the probability of electronic pollution counting in the instrument is less than 1%.The results provide an important reference for the analysis and processing of the data of the intermediate-energy proton detector in orbit.
