Slow wave structure in twt
Webb7 juli 2024 · What are different waves possible in TWT? Therefore, a slow-wave structure is used that causes a reduction in the phase velocity of the RF wave inside the TWT. The slow-wave structures can be of different types like a single helix, double helix, zigzag line, corrugated, coupled-cavity or ring bar type etc. Webb11 sep. 2024 · In TWT, slow wave structures are used instead of resonant cavities as in Klystrons. Working Principle TWT has an electron gun which produces and accelerates the electron beam along the axis of the tube. Surround magnet provides a magnetic field along the axis of tube to focus the electron beam.
