A nonlinear beam-wave interaction has be built to simulate the BWO in Helical traveling wave tube, which is in the above of 1D beam-wave interaction model by field theory, And taking into account of angular speed which are affected by magnetic fields. The CN with different QC has be compared to equivalent circuit in small signal, that the result is close. Also, the simulated results are accorded with...
Using beam wave interaction simulator (BWIS), one module of microwave tube simulator suite (MTSS), a wideband helix TWT has been accurately simulated. The slow-wave circuit parameters are calculated by high frequency circuit simulator.
