矩形波导结构潘尼管工作特性的分析

Working Characteristic Analysis of Peniotron Using a Rectangular Waveguide Structure

本文导出了一般TE_(no)模矩形波导结构潘尼管的色散方程,对潘尼管作了更明确的解释,并详细计算了TE_(20)模潘尼管的色散方程,得到其基波和第三次谐波同步谐振的色散曲线。该曲线表明,潘尼管在基波谐振上有1.5%的增长率,而在第三次谐波上有0.8%的平均增长率。此外,用非线性理论分析基波和第三次谐波同步谐振时的工作情况,给出了电子饱和时的电子分布图。在常直流磁场下优化结果表明,潘尼管在其次谐振时有51%的高效率和QP_w=9949.9MW 的输出功率,而在第三次谐振时有11%的效率和QP_w=1741.8MW 的输出功率。

The dispersion equation of a peniotron using TE_(no) mode in a rectangular waveguide strustureis derived in this paper.The working conditions of the peniotron are investigated and a clearer ex-planation of the peniotron is made.Based on this,numerical calcnlations of the dispersion equa-tion of the peniotron using TE_(20) mode are carried out to get the dispersion curves of the peniotronworking at the fundamental and the third harmonic synchronous resonance.The curves show thatthe peniotron has 1.5% growth rate at the fundamental and 0.8% average growth rate at thethird harmonic resonance.Further more,the performance of peniotron at the fundamental and thethird harmonic resonance are analysed by nonlinear theory,which gives the electron distributionat efficiency saturation.Through large amount of computation,the optimum result is derived:pe-niotro has 51%high efficiency and QPw=9949.94MW output power at the fundametal,and11% efficiency and QPw=1741.8MW output power at the third harmonic resonance.
