Description

technical field [0001] The invention belongs to the technical fields of space physics and space environment detection, and in particular relates to a dual-channel electrostatic analyzer for synchronous measurement of ions and electrons. Background technique [0002] Currently, charged ions and electrons exist everywhere in Earth's space, interplanetary space, and the space of other planets in the solar system. These charged particles are one of the main environmental elements in space. Charged particles can interact with on-orbit spacecraft to cause various space environmental effects such as charging and discharging. The detection of charged particles can be used to study fundamental physical issues of human concern, such as how low-energy particles are accelerated to high-energy particles, and how the sun affects the formation and dissipation of planetary atmospheres. The resolution of these problems will help humans understand and understand the unknown world, and also p...
