TL;DR: In this article , a 95 GHz extended interaction oscillator (EIO) with high voltage was designed and tested in order to obtain a high-power radiation source in the W-band, and the overall structure of the designed EIO was introduced, and simulation results of the slow wave structure were shown.

TL;DR: In this article, the double-groove loaded folded-waveguide slow-wave structure (SWS) was proposed for millimeter traveling-wave tubes (TWTs) to enhance the strength of beam-wave interaction and improve the performance of gain, the expressions for the dispersion and the interaction impedance of this novel structure are obtained by using matching conditions of the RF fields.

TL;DR: This paper gives a introduction to the research activities on the millimeter wave traveling wave tube (TWT) in UESTC, including some development of the novel slow wave structures, the design and experiment work of MM TWT.

TL;DR: In this paper, a novel angular log-periodic groove waveguide slow wave structure (SWS) for 340 GHz traveling wave tube (TWT) is proposed, which could achieve a very low operating voltage and small scale at the same time.

TL;DR: In this article, the radial divergent sheet beam electron optical system focused by a radial uniform magnetic field was designed, which can stably pass through the beam drift tunnel with transverse size of 20 deg×0.52 mm and the length of 20 mm in a radial quasi-uniform magnetic field.
