An Improved optimization method for helix pitch profile in traveling wave tubes has been described in this paper. Regardless the reflection waves effect, the sequence characteristic of the beam-wave interaction calculation and the power saturation index such as field relative phase are integral to the optimization method. By Setting several backup point and using the field relative phase, the beam-wave...
A useful design technique of helix pitch profile for high-efficiency Traveling-Wave tubes (TWTs) is put forward. The purpose of the design technique is to increase the normalized axial growth rate of ac electric field amplitude by selecting an appropriate helix pitch profile and so that the power and efficiency are maximized.
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...
Microwave tube simulator suite (MTSS) is a fully featured software package for microwave tube analysis and design. it consists of four modules now, microwave tube design environment (MTDE), electron optics simulator (EOS), high frequency circuit simulator (HFCS), and beam-wave interaction simulator (BWIS).
