[Abstract]:According to the mission requirements of the electromagnetic monitoring test satellite, a plasma analyzer was developed, and the ionospheric plasma in-situ detection was realized for the first time. As an important part of the plasma analyzer, the retarded potential analyzer is mainly used to detect the ionospheric plasma density, drift velocity, temperature and composition along the orbit. Beryllium copper and gold-plated surface are used as the materials for the sensor grid of the potential arrester, and the consistency between the total transmission rate of the multilayer grid and the theoretical calculation is verified by simulation. According to the technical specifications, the parameters such as window radius, collector radius, effective height and scanning voltage of the sensor are designed in detail. In the design of electronic circuit, the precision of circuit measurement is ensured by the design of three adjustable ranges of forward amplifier circuit. On this basis, the plasma environment test of the retarded potential analyzer has been completed with the help of the ground plasma environment of the interplanetary physics institute of the National Astrophysics Institute of Italy. The test results show that the performance of the block potential analyzer meets the design requirements and can meet the mission requirements of the electromagnetic monitoring test satellite.
