| 摘 要： | 在高导流系数的速调管中电子束径及横向速度都会发生显著变化，运动电子与间隙电场之间的能量交换是非线性的互作用过程.为了能准确描述这些现象，我们建立了相应的物理模型并据此编写了用于速调管注波互作用分析的2.5维程序LSP.随后使用该程序针对一个实际的S波段高峰值功率速调管做了详细的计算，与一维程序的计算结果和实测数据的比较表明LSP程序的计算值具有更好的准确性且与实测值很好地一致.

| Abstract: | In high perveance klystrons, violent variation of electron beam radius and electron transverse velocity is met with, and the energy exchange between kinetic electrons and gap field is a nonlinear process. For accurately describing these physical phenomena, we have put forward the corresponding physical model and further developed the 2.5-dimensional computation program LSP. Moreover, by use of this tool, we analyzed a practical S-band high peak-power klystron in detail. By comparing with the calculation results using 1-dimensional program and experimental data, we noticed that this poly-dimensional program can approach the real situation with higher precision. |
