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.
In high-klystron klystron, the electron beam diameter and lateral velocity change significantly, and the energy exchange between the moving electron and the gap electric field is a nonlinear interaction process.In order to describe these phenomena accurately, we establish the corresponding Physical model and accordingly prepared 2.5-dimensional program LSP for the analysis of the klystron wave interaction in the klystron.Then the program was used to do a detailed calculation for an actual S-band high peak power klystron, Comparisons between the calculated results and the measured data show that the calculated values of the LSP program have better accuracy and are in good agreement with the measured values.
