| 1 | The high-energy particle package onboard CSES显示文摘Introduction The China Seismo-Electromagnetic Satellite(CSES)aims to monitor space electromagnetic fields,ionospheric plasma,high-energy charged particles and other features of the global space environment.The high-energy particle package(HEPP),which can effectively detect the energy spectrum,flux and pitch angle distribution of space electrons and protons,and soft X-ray emission from solar flares,is one of the main payloads of CSES.Purposes and methods In this study,we designed,developed and calibrated the high-energy particle package and launched it into orbit with CSES.HEPP consists of the high-energy detector(HEPP-H),the low-energy detector(HEPP-L),and the solar X-ray monitor(HEPP-X).The three sub-detectors mainly use silicon detector and crystal calorimeter detection technology.Before launching,we calibrated the three sub-detectors in detail by using radiation source and accelerator beam.Results All the three sub-detectors have good energy linearity.After launching into orbit,the space energetic particles and X-ray distribution detected by HEPP are consistent with expectations.The performance indices of the detector reach the advanced level of the same kind of detector in the world.Conclusions HEPP has a wide energy detection range,good energy resolution and high angular resolution ability for electrons and protons.It will play an important role in the study of space particle response and space physics of seismic activity. | X.Q.Li Y.B.Xu Z.H.An X.H.Liang P.Wang X.Y.Zhao H.Y.Wang H.Lu Y.Q.Ma X.H.Shen X.Y.Wen H.Wang D.L.Zhang F.Shi W.X.Peng M.Gao X.X.Yu J.Z.Wang Y.J.Zhang J.L.Zhang J.Zhang H.X.Li J.R.Zeng Y.F.Nan | 2019 | Radiation Detection Technology and Methods2019，3，3： | 0 |
