Abstract :
In this paper, authors have presented design and development of a S, C band 200 W, 2-6 GHz CW helix travelling wave tube (TWT) with saturated gain of 40 dB. In the TWT, wide bandwidth is achieved when helix is used as a slow wave structure. The electron gun of this tube is a Peirce convergent type tube. The electron trajectory of the electron gun was showed. Power and gain response of TWT were investigated. Variation of phase velocity and interaction impedance with frequency for different helix pitches were studied.
