摘要：The measurement of energetic particles plays an important role in the space environment monitoring and space weather *** accuracy of the energetic electron measurement is seriously influenced by the proton *** anti-proton contamination design for the sensor of imaging energetic electron spectrometer is introduced in this *** 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.

摘要：The Dst index,designed as a proxy of ring current intensity,is known to be also affected by other magnetospheric current systems,*** *** pressure-corrected Dst index is obtained by removing the effects of the solar wind dynamic pressure and the quiet time ring ***,all previous studies treated the correction coefficient as an averaged parameter for storms of different *** this paper,based on the Burton's equations and employing two independent methods,we will show a positive correlation between pressure-correction coefficient b and the intensity of the *** divided our storm database(872 storms in total) into three categories according to the intensity of *** order to improve the accuracy of calculating,we also used the higher-resolution SYM-H index data instead of Dst index to compute the corrected Dst index during different ***,we are able to provide corrected magnetic storm index with high-time resolution(-1 min).
