摘要： 由于偏转系统结构复杂,并加有铁磁材料,因此采用FEM计算具有许多优越性。偏转系统中偏转场的分布没有明确的边界,应做为开域问题处理。结合偏转场的一些自身特点,提出采用FEM-BEM计算偏转场,该方法与一般的混合法不同,它既保证了偏转轨迹的计算准确性,同时又减小了对计算机计算速度和内存的要求
关键词: 偏转系统, FEM, BEM, 电子轨迹
Abstract: Since the structure of deflection system is complicated, FEM (Finite Element Method) may be suitable to calculate the system. However, the deflection field has no definite boundary, it must be taken as an open boundary problem. In view of some peculiarities of deflection system, an improved method FEM-BEM is proposed for analysis. This method is different from ordinary hybrid method, it not only improves the accuracy of deflection traces, but also decreases the requirement for computer speed and memory.
Key words: deflection system, FEM, BEM, electron trace
