【摘要】 本文应用EGS4模拟计算程序,计算了通过双层金属箔结构式钛窗的引出系统,电子束的能量效率和束流效率,与国外的计算结果符合得较好。进一步针对烟气除硫用大功率电子加速器引出系统,详细模拟了在不同加速电压下,电子束通过钛窗之后能量分布、角度分布以及X射线产生额度和钛窗发热等特性,计算了烟气除硫用人功率电子加速器引出系统的电子束引出效率。更多还原

【Abstract】 This paper calculated the electron beam’s energy and efficiency when passing the two-layers titanium window, using EGS4 code. The results can match the experiment well. Further on the background of extraction system of high-power electron accelerators, which can be used to eliminate sulfur from gas, energy distribution, angle distribution, X-ray generating proportion, titanium window’s heating, were simulated in the condition of different accelerating voltages, and extraction efficiency was obtained.更多还原
