摘　　要：利用ANSYS软件对盒栅式倍增系统打拿极三维电场分布进行了建模,计算了打拿极附近电势分布情况。通过对比不同模型的计算结果,对影响盒栅式倍增系统打拿极电场分布的因素进行了研究。结果表明,打拿极的结构布局和栅网宽度对电场分布的影响较大。Model of a box type multiplier system was established and the electric field was calculated by ANSYS software.The factors that had effect on the distribution of three-dimensional electric field were researched by comparing the results.It shows that the configuration of the dynodes and the width of the bars can greatly affect the distribution of the electric field.
