Description

technical field [0001] The invention relates to the field of aerospace, in particular to a ground simulation device and method for deep charging of space protons. Background technique [0002] Space high-energy charged particles easily deposit charges inside the dielectric material on the surface of the spacecraft or pass through the shielding layer of the spacecraft to deposit charges on the dielectric materials and suspended conductors inside. It is the deep charging or internal charging effect of the spacecraft. [0003] A large number of space flight tests have shown that the deep charging effect is one of the important causes of spacecraft on-orbit failures. In low Earth orbit, the deep charging effect is mainly caused by energetic electrons in the Earth's radiation belts. In the interplanetary deep space orbit, the radiation environment encountered by the spacecraft mainly comes from galactic cosmic rays (GCR) and solar proton events (SPE). GCR is a charged particle...
