Technical Field

The invention relates to the technical field of ground simulation of a space comprehensive environment, in particular to a multi-energy electron proton and solar radiation comprehensive environment simulation system, and particularly relates to a multi-energy electron proton and solar radiation comprehensive environment simulation system constructed by a certain technical means.

Background

The spatial radiation particle components are mainly electrons, protons and a small number of heavy ions, with energies ranging from 1keV to several hundred MeV, and even up to several GeV, the higher the energy the smaller its flux. Because the energy range of the space charged particles is wide, and the energy distribution and flux of the particles can be dynamically changed along with factors such as the sun, geomagnetic activity and the like, the real space radiation environment cannot be completely simulated in the ground simulated space radiation environment.

Generally, low-energy particle radiation (below 1 MeV) only affects the change of the surface of a substance, and the particle radiation with energy of 1-10MeV can cause the change of the internal structure of the substance, so that the research on the damage mechanism and law in the substance is necessary. The range depth of the proton radiation above 10MeV is increased along with the increase of the energy, and a more remarkable ionization effect is generated on the track or the ionization effect is generated due to recoil particles in the material, so that a single event effect occurs.

The irradiation platform is arranged in an irradiation chamber close to vacuum for testing, the beam output of the electron accelerator can be changed in a large range, and comprehensive state simulation and accurate parameter measurement can be realized.
