电子束发射诱发航天器充电的数值模拟研究
Numerical simulation on spacecraft charging due to electron beam emission
摘要
Abstract
Measuring the geomagnetic field in space by emitting electron beams is a new and effective high-precision measurement method of the geomagnetic field,but the emission of electron beams has an impact on the state and safety of the spacecraft.To study the influence,based on the orbit-limited mechanism,the model of spacecraft charging due to high-energy electron beam emission was studied,and the potential balance formula under different initial potentials was derived,and a program was compiled to study the impact of particle beam current,energy,light electron and other factors affecting the spacecraft charging potential.The time-varying law of the charging potential induced by the spacecraft itself or the platform when the spacecraft emits high-energy electron beams is obtained,and the correctness of the simulation results is verified by the partial analytical solution comparison.关键词
