摘　　要：采用CST三维电磁仿真软件对侧窗型光电倍增管的电子倍增系统进行建模与仿真,研究了阳极位置和阳极尺寸对该系统增益、上升时间、电子渡越时间的影响,并通过相关参数的优化,提升了电子倍增系统的增益和时间特性。仿真研究发现,基于增益和时间特性的综合考虑,阳极中心位于(2.92 mm,8.99 mm)位置且阳极直径为0.6 mm时,电子倍增系统性能较优。通过阳极位置和尺寸的优化,电子倍增系统增益达7.93×10~6,增大了60.85%;上升时间达1.3 ns,基本保持不变;电子渡越时间达17.1 ns,减小了2.84%。An electron multiplication system of side-on photomultiplier tubes is modeled and simulated by using CST three-dimensional electromagnetic simulation software,and the effects of the anode position and anode size on the gain,rising time and electron transit time of the electron multiplication system are investigated.The gain and time characteristics of the electron multiplication system are improved through the optimization of the relevant parameters.The simulation investigation reveals that,based on the comprehensive consideration of the gain and time characteristics,the electron multiplication system performs better when the anode center is located at the position of(2.92 mm,8.99 mm)and the anode diameter is 0.6 mm.By optimizing the anode position and size,the electron multiplication system gain reaches 7.93×106,increased by 60.85%;the rising time reaches 1.30 ns,basically unchanged;and the electron transit time reaches 17.10 ns,decreased by 2.84%.
