摘　　要：开展了具有同轴波纹渐变式反射器与光滑漂移段结构的相对论绕射辐射振荡器的研究,并运用全三维粒子模拟软件CHIPIC对其进行数值模拟仿真,分析了漂移段、反射器等结构对输出功率的影响,探讨了反射器位置和输出功率的关系。仿真结果表明:合适的漂移段与反射器的引入,能大大提高输出功率。优化结构参数,在输入电压480kV下,平均输出功率达到774.5MW,平均功率效率为32.3%。A coaxial corrugated reflector and smooth drift segments structure of relativistic diffraction generator were stud- ied using the full three-dimensional particle simulation software CHIPIC. The influences of the drift segments and reflector on the output power were analyzed. The relationship between the reflector position and the output power was explored. The simulation results show that appropriate reflector and drift segments can greatly improve the output power. After optimization of the struc- ture parameters, when the input voltage was 480 kV, the average output power achieved 774.5 MW and the average power effi- ciency attained 32.3 %.
