摘要： 在把微波电子回旋共振（ＥＣＲ） 技术应用到离子源中， 获得了１０１５个原子／ （ｃｍ ３·ｓ） 束流的基础上， 采用了结构新颖的降能和中性化系统， 把高能氧离子转变为低能氧原子； 成功地研制出了一种新颖的原子氧环境效应地面模拟试验装置。由该装置获得的粒子在能量和类型方面均与低地球轨道环境相一致， 从而实现了对低地球轨道环境的真实模拟。

Abstract: By using an advanced Electron Cyclotron Resonance (ECR) technical, an ion source with 10 15 /(cm 3·s) has been attained. On the base of it, a new atomic oxygen simulator is developed successfully. There are deceleration and neutralization systems in this simulator, so that oxygen ion beam with high velocity can been converted into oxygen atom beam with low velocity. Energy and types of the particles in this simulator are similar that of LEO. Thus a real simulation of Low Earth Orbital environment is accomplished.
