高能粒子的测量在空间环境监测和空间天气预报中起着重要作用。质子污染严重影响了高能电子测量的准确性。本文介绍了一种用于成像高能电子能谱仪传感器的抗质子污染设计。根据辐射带模型计算出的典型卫星轨道上的电子和质子能谱,利用Geant4模拟软件对防质子污染设计的效率进行了估算,并根据模拟结果对设计进行了优化。
The measurement of energetic particles plays an important role in the space environment monitoring and space weather forecasting. The accuracy of the energetic electron measurement is seriously influenced by the proton contamination. An anti-proton contamination design for the sensor of imaging energetic electron spectrometer is introduced in this paper. According to the electron and proton spectrum on the typical satellite orbits calculated by the radiation belt models, the efficiency of the anti-proton contamination design is estimated by the Geant4 simulation and the design is optimized based on the simulation results.
