| Abstract: | The paper has 3D nonlinear analysis for TWTs. Based on macro particle model, the electron beam can be subdivided into 3D Macro particles to calculate space charge forces using Green's function methods, and 3D large signal working equations are obtained. The numerical results for a uniform magnetic focusing field indicates that, in 3D numerical analysis, 3D space charge forces can be substituted by 2D's with little influence on the numerical results, which greatly decreases computing hours so that 3D computer program can be easily used. |
