本文介绍了优化新开发的20英寸的模拟工作。通过增大两个聚焦电极的外径和玻壳的开口面积，研究了偏置电压对聚焦电极和MCP输入面的影响。20英寸的新设计。MCP-PMT，其渡越时间分布小于3 ns，收集效率与现有样机相当。
This paper describes the simulation work for optimizing the newly developed 20-in. elliptical MCP-PMT by enlarging the outside diameters of the two focusing electrodes and the open area of the glass bulb. Effects of biasing voltages applied to the two focusing electrodes and the MCP input facet are studied. With the new design of the 20 in. MCP-PMT, the transit time spread of the prototype can be less than 3 ns and the collection efficiency is as much as the present prototype.
