An Upgraded 4 Meters Long Traveling Wave Tube for Plasma Physics Research

At previous IVEC conferences, we presented a new Nbody time-domain model for simulating traveling wave tubes (TWTs), which has been applied and assessed for several industrial TWTs covering a broad range of bandwidth and power regimes. Since then, we applied this model to meters long TWTs operating far beyond the saturation point. The capacity of our algorithm DIMOHA to predict correctly non linear behaviours is assessed against measurements for a 200 MHz, 3 meter long TWT.

An Upgraded 4 Meters Long Traveling Wave Tube for Plasma Physics Research

Abstract: We consider a 4 meters long traveling wave tube (TWT) that presents an upgraded slow wave structure. We analyze linear and nonlinear phenomena due to the beam-wave interaction in the device, e.g. beam modulation, and wave growth and saturation.
