1.
The results show that changing the potential and diameter of focus electrode,and the space between the grid electrode and focus electrode doesn t affect the electric field seriously,but has strong influence on electron trajectory.
结果表明,聚焦极电位、聚焦极孔半径及聚焦极与栅极间距的变化对锥尖电场影响不大,但对电子轨迹影响很大。
5) focusing grid
聚焦栅极
6) image focusing electrode
像聚焦极
