【摘要】 在高增益的注入式正交场放大器中,慢波线中的切断区是必不可少的。本文提出了一个关于密度调制电子注经过切断区内的漂移过程及在切断区出口慢波结构上重新感应激励高频场的物理模型,给出了数学推导和理论公式,编制了FORTRAN语言的计算机程序,计算结果相对与实验的误差为7％～20％;一系列计算结果显示了切断区长度、位置及切断区内电子漂移过程对输出功率的影响。本文提出的计算方法和计算机程序,可供此类器件的计算机辅助设计之用。更多还原

【Abstract】 A physical model and related formulas describing the drift process of a density modulated electron beam through the sever and the build up of RF field on the slow wave system beyond the sever are presented in this paper. Computed results show that the difference of output power between theoretical and experimental values is around 7-20%, which varies from tube to tube. Systematic study reveals the effects of the length, location and the drift process in the severs on the output power.The technique and program used in this work can be applied, for CAD of IBCFA.更多还原
