在IOM Leipzig，我们开发了一个高效的网格侵蚀模拟代码。在我们的方法中，离子束提取和网格侵蚀发生在一个多网格多孔径离子推进器中，我们将相关基本过程的复杂相互作用分解成连续的步骤。在小型宽束离子源的离子光学和短时网格侵蚀测量的基础上，对该程序进行了全面的实验验证。测量数据和模拟数据之间的良好一致性为该方法提供了信心。
At IOM Leipzig, we developed an efficient grid erosion simulation code. In our approach to ion beam extraction and grid erosion occurring in a multi-grid multi-aperture ion thruster we break down the complex interplay of pertinent elementary processes into consecutive steps. On the basis of ion optical and short-time grid-erosion measurements on a small broad-beam ion source, a comprehensive experimental validation of this code has been done. The good agreement between measured and simulated data furnishes confidence in the methodology.
