论文摘要
将微瘤网格的电子透明度的测量与模拟进行了比较。显示通量保护参数显示导致透明度的不准确估计值，讨论了网格的准确几何建模的重要性，并证明了网格的偶极矩的效果。这项研究提供了专门针对微型图案开发的显微模拟方法的验证，在该方法中，特征尺寸的数量级与气体中的电子平均自由路径相同。
Measurements of the electron transparency of a Micromegas mesh are compared to simulations. The flux conservation argument is shown to lead to inaccurate estimates of the transparency, the importance of accurate geometric modelling of the mesh is discussed and the effect of the dipole moment of the mesh is demonstrated. This study provides a validation of the microscopic simulation methods specifically developed for micropattern devices where the characteristic dimensions are of the same order of magnitude as the electron mean free path in the gas.
