The dependence of the cold parameter on the configurations of cavity was analyzed. For the particle in cell (PIC) simulation analysis, the optimized cavity frequency combination of eight-cavity WSBK circuit was obtained using 2-D software SBK2D, which runs with speed,, thereby allowing an efficient investigation of input parameters. To unify the electronic-beam wave interaction system's hot parameter design, the calculation results are examined by PIC simulation (MAGIC-3D), and show good agreement with CST, thereby confirming the design method mentioned above. These results provide key parameters and a good foundation for developing higher performance on RF structure of sheet beam klystron in the future. 参考文献 相似文献 引证文献
