【Abstract】 A multi-functional spectrometer-identificator was developed for studying fluxes and spectra of protons,alpha particles,oxygen and iron ions in the near-earth space.The telescope system of this spectrometer consists of three Au-Si surface barrier detectors with different thickness and scintillation CsI(Tl).Owing to adopting the ΔE～E method in particles identification and improved fast response electronics system in data processing and acquisition system,the spectrometer can be used to simultaneously and separately detect the fluxes and spectra of protons of 1～200 MeV,alpha particles of 1～200 MeV/u(nucleon),oxygen ions of 1.7～496 MeV/u and iron ions of 2.5 MeV～1.0 GeV/u.更多还原
