Reflections in Traveling Wave Tubes: Simulation Using the 1-D Time-Domain Hamiltonian Model DIMOHA With Experimental Validation

Year: 2024

Type: article

Abstract: DIMOHA is a many-particle time-domain model offering a good balance between exhaustive physics and time efficiency. We apply this model to study the effects of defects and reflections in the slow wave structure (SWS) of a traveling wave tube (TWT). To assess DIMOHA’s validity, we set up a TWT with varying reflection coefficients at the tube’s end. A ripple effect in saturated output power with respect to frequency is measured and simulated self-consistently with a rough agreement.
